Fix a non-ANSI prototype.

[nmh] / ChangeLog

2005-11-09  Peter Maydell  <pmaydell@chiark.greenend.org.uk>

        * h/aliasbr.h: fix a non-ANSI prototype.

2005-11-08  Oliver Kiddle  <okiddle@yahoo.co.uk>

        * Simon Burge: acconfig.h, configure.in, uip/rcvtty.c, uip/slocal.c:
        fix to handle getutent() on NetBSD

        * INSTALL, README, docs/README.about, man/nmh.man: update most
        references to the web page and mailing list locations

        * bug #10230: etc/Makefile.in, man/Makefile.in, uip/Makefile.in:
        Michael De La Rue: prepend DESTDIR to install locations

        * configure.in, */Makefile.in, mts/smtp/smtp.c: replace obsolete
        autoconf macros

2005-11-06  Peter Maydell  <pmaydell@chiark.greenend.org.uk>

        * sbr/fmt_rfc2047.c, sbr/fmt_scan.c, h/prototypes.h: fix various
        possible overruns of the buffers in fmt_scan() which would cause
        crashes if scan was run with '-width 16536' or similar.

        * uip/popsbr.c: fix compile error which only showed up if nmh
        was configured with --enable-apop.

        * Debian Bug# 245932, RedHat Bug# 172388: uip/mhparse.c: don't
        crash when handling a multipart MIME message with an invalid
        Content-Type header (file handle was being fclose()d twice).

        * sbr/Makefile.in: adjust lex command to work on both old and
        new versions of flex.

        * configure.in: add an AC_PREREQ() so autoconf 2.13 gives a helpful
        error message and the Debian autoconf-version-guessing wrapper
        doesn't guess wrongly.

2005-11-02  Oliver Kiddle  <okiddle@yahoo.co.uk>

        * Debian Bug# 320069: Nick Rusnov: uip/popsbr.c: fail when
        kpop connection attempted without KPOP support compiled in

        * Debian Bug# 320090: Nick Rusnov: sbr/Makefile.in: fix for newer
        version of flex and remove autogenerated file from cvs

        files with numbers as names

        * docs/Makefile.in: include new files in distribution

2005-10-11  Bill Wohler  <wohler@newt.com>

        * docs/FAQ: fold questions into MH FAQ and distribute that instead

2005-10-05  Oliver Kiddle  <okiddle@yahoo.co.uk>

        * Harald Geyer: h/mh.h, uip/replsbr.c: back out previous change
        (fork/vfork) and replace with code that handles the issue directly

2005-05-18  Oliver Kiddle  <okiddle@yahoo.co.uk>

        * Debian Bug# 143485: Nick Rusnov: h/mh.h: use fork instead of
        vfork on Linux

        * Debian Bug# 261592: Harald Geyer: uip/mhlsbr.c, uip/replsbr.c:
        test/report error writing to stdout

        * mts/smtp/smtp.c, uip/popsbr.c: correct SASL include file locations

        * docs/COMPLETION-BASH: bash completion definitions from Debian

        * patch #2863: savannah@brisammon.fastmail.fm: sbr/folder_read.c:
        fix a bug affecting AFS where nmh was setting the READONLY flag
        for a folder even when you do have write access to the folder

        * Carl Mummert: h/fmt_compile.h, man/mh-format.man,
        sbr/fmt_compile.c, sbr/fmt_scan.c: add unquote() function for
        removing quotes from RFC-2822 encoded headers

2005-02-23  Oliver Kiddle  <okiddle@yahoo.co.uk>

        * use iconv to convert RFC-2047 encoded headers to the
        character set used by the current locale

        * sbr/folder_read.c fix Debian bug #202667: crash when a
        message's filename overflows an int when converted

        * Updated config.guess and config.sub to the most recent
        versions (from automake 1.9.5)

2005-02-21  Oliver Kiddle  <okiddle@yahoo.co.uk>

        * sbr/getpass.c fix bug where inc crashed on failing to reopen
        the terminal

2005-01-27  Oliver Kiddle  <okiddle@yahoo.co.uk>

        * Added -proxy option to inc and msgchk. Based on old patch
        from Michael Richardson.

        * On systems where it is available, use nl_langinfo to get the
        character set if MM_CHARSET is unset

2005-01-21  Oliver Kiddle  <okiddle@yahoo.co.uk>

        * sbr/check_charset.c US-ASCII is a subset of UTF-8 so can be
        handled directly when UTF-8 is being used

2004-12-17  Oliver Kiddle  <okiddle@yahoo.co.uk>

        * uip/mhmisc.c Fix -part option to mhshow/mhlist/mhstore to
        find sub-parts of the specified part

2004-11-19  Jon Steinhart  <jon@fourwinds.com>

        * h/prototypes.h, sbr/folder_addmsg.c, uip/mhstoresbr.c,
        uip/rcvstore.c, uip/refile.c: Added mail directory argument to
        folder_addmsg in order to make it possible to provide a path to
        the ext_hook call that is mailpath-based.  A problem existed when
        a folder was a symbolic link and the pwd call would return the
        path relative to the filesystem, not to mailpath.  A new argument
        was needed because there was otherwise no reasonable way to get
        that path.

2004-11-16  Jon Steinhart  <jon@fourwinds.com>

        * sbr/folder_pack.c: Fixed problem where the refile hook was being
        called after a message was renamed so that it wasn't around for
        the hook.  The hook is now called before the message file is
        renamed.

        * sbr/folder_addmsg.c: Fixed wrong directory for hook when
        refiling with -src option.

2004-10-15  Jon Steinhart  <jon@fourwinds.com>

        * uip/sortm.c: Fixed calling of external hooks.

2004-10-12  Jon Steinhart  <jon@fourwinds.com>

        * uip/inc.c: Fixed another weird bug caused by the static
        mailpath being overwritten.

        * uip/sendsbr.c: Fixed bug that caused anno to mangle headers.

        * sbr/lock_file.c: Fixed strange bug that prevented a lock from
        ever being obtained if getting it failed the first time.  The
        problem was that the string of XXXXXX that is required by
        mkstemp() was overwritten the first time through, and so all
        subsequent times failed because mkstemp() failed.  The fix
        reinitializes the tmp file string.

        * uip/inc.c: Fixed bug in which the static maildir was overwritted
        if a format string was read from the profile.

        * sbr/folder_delmsgs.c: Fixed bug that was producing an incorrect
        path for the external hook.

2003-10-06  Glenn Burkhardt <glenn@aoi-industries.com>

        * uip/slocal.c, configure.in: db configuration fix for Debian; yet
          another location for ndbm.

2003-09-30  Glenn Burkhardt <glenn@aoi-industries.com>

        * Fix 'pick' so handling of options "-list" and "-seq" are
        independent.
        * Fix 'inc' realloc error when bringing in more than 100 msgs
        to empty folder.
        * Patches submitted by Nick Rusnov from Debian archive applied:

        Debian Bug#
           136976 - Handle binary content messages
           143427 - mh-format.man typo
           144098 - 'spost; should have same behavior as 'post'
                    w.r.t. mts.conf masquerade line
           149745 - slocal ignores 'N' result of previous command
           152728 - increase SMTP timeouts to conform to RFC 1123
                    The timeouts suggested by the RFC seem long
                    to me - but the RFC is still listed as active.
           181867 - typo for nmh.man
        
2003-08-10  Jeffrey C Honig  <jch@honig.net>

        * Fix problem where parsing of address/date fields in fmt_compile
        is optimized to the first instance.  The first instance may be in
        contitional code which will result in cached data to
        be used.  Instead, convert c_flags to a flags field from a boolean
        and parse on the first use.
        * Remove some unused flag bits.

Fri Jul 01 22:02:00 2003 Glenn Burkhardt <glenn@aoi-industries.com>

        * Applied fixes for configuration problems with Solaris and
          systems with gdbm instead of db1 (includes bug #2024)
        * Fixes for bugs 
          #578  - repl leaks umask 
          #1393 - sortm core dumps 
          #1650 - msh leaks file descriptors
          #1730 - Double free() in mhfree.c:free_encoding()
          #3356 - In-Reply-To header in default replcomps should be 
                  RFC2822 compliant 
        * Revised man page for mh-format (bug #2031)
        * New replcomps, etc, with Fcc: +outbox in default versions
        
Sat Mar 17 03:18:15 2001 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Ken Hornstein's configure.in Cyrus SASL checks were doing 
        `x"$with_cyrus_sasl" != "no"' instead of `... != x"no"'.

Tue Mar 06 21:04:27 2001 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Found some historical information about MH in RFC 808.
        Supplemented it with info from Jerry Peek's MH book and added it
        to docs/README.about.

Tue Feb 6 20:35:40 2001 Shantonu Sen <ssen@mit.edu>

        * sbr/dtime.c Use the same Y2K correction code as dtimep.lex

        * sbr/dtimep.lex Restrict the parser to accept either
        a numerical timezone offset, or a symbolic one (e.g. EST),
        but not both (Since "2000 -400 EDT" might cause a double
        subtraction of 60 minutes if both are parsed. One should be
        enough).

Mon Feb 05 20:22:54 2001 Dan Harkless <dan-nmh@dilvish.speed.net>

        * -L isn't sufficient for specifying the path of the Cyrus SASL
        shared library.  That'll allow us to link successfully, but on
        many/most OSes that won't allow us to find libsasl at runtime.  On
        Solaris, we need to specify the library path with -R as well (or
        else the user will have to use the $LD_LIBRARY_PATH kludge, which
        is considered harmful).  This fix should be extended to other OSes
        as well.

        * Print whether we have SASL support in the "nmh configuration"
        summary configure prints out.

        * Say in README.developers to use `\date' in case anyone is like
        me and has `date' aliased in their shell to use a nonstandard (but
        subjectively more readable) format.

Thu Jan 25 21:15:52 2001 Shantonu Sen <ssen@mit.edu>

        * man/mh-chart.man has updated synposes of
        all nmh commands.

Tue Jan 23 20:26:15 2001 Shantonu Sen <ssen@mit.edu>

        * etc/digestcomps tried to force dates into a
        19xx when it's not necessary.
        
Fri Jan 19 21:22:08 2001 Shantonu Sen <ssen@mit.edu>

        * First round of manpage updates finished. They
        are standardized on -man macros, with minimal
        roff mark-up.

        * man/tmac.h.in is no longer needed, since the
        manpages do not depend on them anymore. Note:
        strict "man" programs that didn't allow ".so"
        sourcing outside the man tree will now format
        the man pages correctly.

        * man/vmh.1 is no longer built, since uip/vmh isn't
        
Tue Jan 9 6:01:22 2001 Shantonu Sen <ssen@mit.edu>

        * Finished manpages ali-prev

        * Removed deprecated files from the repository.
        Specifically, those rooted in zotnet/ and mts/sendmail
        mts/mmdf. "cvs update -dP" will give a pruned directory
        structure.

        * Updated docs/Makefile.in to include README.manpages, and
        uip/Makefile.in to include popi.c (which isn't being built,
        though). This allows "make nmhdist" to create an archive that
        is file-for-file identical to the current cvs repository.

Sun Dec 31 20:48:50 2000 Shantonu Sen <ssen@mit.edu>

        * Create docs/README.manpages, which details
        the formatting rules I've been using.

        * Finished ali-inc.
        
Sat Dec 30 9:50:13 2000 Shantonu Sen <ssen@mit.edu>

        * Created a new file "DATE" to hold the date
        of the most recent nmh release. This date will be
        used in the manpages.

        * Updated docs/README.developers to add the step
        of updating DATE. Also, updated configure to
        read in the contents of the file as the variable
        $DATE.

        * Started work on updating man pages, with only
        ali finished so far. Changes: 1) no dependence
        on an external macro file, 2) uses only
        -man macros (although I may be mistaken in this),
        3) syntax in the SYNOPSIS is a little more
        in line with standard UNIX documentation, such as
        bold flags and italicized parameters.

Sun Dec 24 10:06:30 2000 Shantonu Sen <ssen@mit.edu>

        * Updated INSTALL with information about the
        --with-locking option.

        * Fixed the Hesiod tests in configure.in. In
        systems where res_send was in -lresolv, this
        information was not being communicated to the
        HESIOD_LIBS var. Now, if res_send is not found
        in the default libraries, it's assumed to be
        in -lresolv, and thus -lresolv is appended to
        HESIOD_LIBS, which will need that to avoid
        undefined symbols problems.

        * Fixed the Kerberos tests in configure.in. New
        versions of Kerberos 5 have renamed -lcrypto
        to -lk5crypto (circa krb5 1.1 or thereabouts). The
        new test tries to determine if -lk5crypto exists. If so,
        this is a new krb5 system. If not, test for -lcrypto
        and the rest of old krb5. If that fails, look
        for a genuine krb4 installation.
        
Fri Dec 22 22:08:51 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * -apop and -noapop were not documented in msgchk.man.
        -snoop was documented but didn't appear in the usage SYNOPSIS.

Fri Dec 22 23:42:16 2000 Shantonu Sen <ssen@mit.edu>

        * Made a new ./configure option called
        "--with-locking" that allows the file
        locking mechanism to be chosen there instead of
        requiring a manual edit of config.h.

        * If the option is not explicitly set, or an
        invalid option is specified, "dot" locking is
        chosen. Valid options are "dot", "fcntl",
        "flock", and "lockf". We need a way to tell
        the user that these are the valid options, and
        change the flag "--with-locking" if it's not
        descriptive enough.

Fri Dec 22 19:21:29 2000 Shantonu Sen <ssen@mit.edu>

        * Remove the lex-specific memory hints at the
        beginning of sbr/dtimep.lex. We've already
        committed to supporting flex only, since
        lex does not easily allow us to parse a single
        string, as well as other problems documented
        below and on nmh-workers.

        * Added a switch statement to configure.in to
        test for Mac OS X. If this is the case, LDFLAGS
        should not contain "-s" since the linker rejects
        the flag.

        * Updated MACHINES to include Mac OS X Public Beta,
        as well as Linux 2.4 running glibc 2.2.

Wed Dec 20 16:00:46 2000 Shantonu Sen <ssen@mit.edu>

        * Marked deprecated directories in docs/README.developers
        as deprecated, with pointers to the new code location.
        Eventually these deprecated directories should go away.

Tue Dec 19 19:16:37 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * -apop and -noapop were not documented in inc.man.  -snoop was
        documented but didn't appear in the usage SYNOPSIS.

Thu Dec 14 14:32:09 2000 Shantonu Sen <ssen@mit.edu>

        * Updated config.guess and config.sub to the most recent
        versions on ftp://ftp.gnu.org/pub/gnu/config, dated
        12-07-00. This should prevent configure from failing
        on newer operating systems because config.{guess,sub}
        couldn't correctly identify them.

Thu Dec 14 1:30:44 2000 Shantonu Sen <ssen@mit.edu>

        * Fixed the circular dependency created when I moved
        zotnet/mts to mts/generic and merged them into libmts.
        mts/generic/client.c and mts/generic/mts.c are now in sbr/
        (and thus in libmh), which makes libmh self-contained and
        not depending on an external archive.

        * All include statements now look for mts.h in h/. The
        Makefiles and configure script have been modified so that
        mts/generic is no longer built.

Mon Dec 11 22:08:07 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * When Shantonu made the new libmts.a, he swapped $(MTSLIB) and
        libmh.a in sbr/Makefile.in so that libmh.a comes first, but this
        causes the build to fail on Solaris, because libmts.a has to get
        ruserpass() out of libmh.a.  Swapping them back to the way Ken
        Hornstein's patch (which I applied on Jul 20) put them, with
        libmh.a correctly coming second.  If there are times when libmts.a
        needs to come second, then it would appear there's a circular
        dependency and someone (Shantonu?) did an mts merge incorrectly.

Fri Sep 8 01:36:23 2000 Shantonu Sen <ssen@mit.edu>

        * Took out bad time textual time zones like BST and JST.
        I found them online somewhere, but am not sure if they're
        correct.        
        
Fri Sep 8 00:36:48 2000 Shantonu Sen <ssen@mit.edu>

        * Moved zotnet/mts to mts/generic. This code reorganization
        makes the entire zotnet tree deprecated -- bboards is unneeded,
        mf was was moved to sbr, tws was rewritten and moved to sbr, and
        now finally mts.

        * Created a new static library called libmts.a used during
        compilation which includes the generic mts code and the
        smtp/sendmail code. This supercedes the functionality of the
        old libsmtp.a and the remains of libzot.a.

        * Updated header includes to reference the new location of mts.h
        in mts/generic/mts.h. Also, update the configure and top-level
        Makefile not to descend into zotnet. Also, they don't descend
        into mts/mmdf and mts/sendmail (the sendmail code has been
        merged into the smtp code).

        * Added #include <h/nmh.h> to h/md5.h, since my compile was
        complaining about implicitly-declared memcpy and memset, which
        appear to be in strings.h. In any event, nmh.h should take care
        of it for us.

        * When doing a "make nmhdist", notice that the generated
        snapshot does not include zotnet of the mts directories as noted
        above. Since they are no longer compiled, and I don't see any
        obvious code path to get to them, end-users should probably
        not need them. If you think otherwise, turn Makefile generation
        back on in configure.in and turn on recursion into those dirs
        in the appropriate Makefile.in

Wed Sep 6 22:40:03 2000 Shantonu Sen <ssen@mit.edu>

        * Tracked down the problem in the new dtimep where time
        zones were being radically misreported. It was because the
        parser knew about military time zones (such as M or E) but in
        some cases did not know about the textual representation of
        some zones (like MET). When it encountered one of these, the
        date parser misread MET as the military time zone T (well, first
        zone M, then E, and finally T). I took military zones out, and
        things seem much better. Also, the default behavior of parsing
        time zones appears to default to GMT in the absence of better
        info, which is less bogus than assuming the mail came from the
        current time zone, which was the behavior in 1.04.

Thu Aug 10 13:22:13 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Decided that limiting the message number columns to 3 on my
        scan.MMDDYY and scan.YYYYMMDD (to try to regain space taken by
        extra date info) was ill-conceived.  It's not that tough to get
        past 999 messages, though I imagine it's rather rare to exceed
        9999.  Changed these to 4.  Also put the "replied / encrypted"
        column back in YYYYMMDD -- I've never seen it show anything but a
        space, but that space is useful if you use scan, grep, and awk
        (with the default field separator) to grab message numbers (I know
        -- pick should really be used for these purposes...).

Mon Aug  7 20:11:09 CEST 2000 Ruud de Rooij <ruud@ruud.org>

        * Modify umask set by mhshow to enable user execute bit, so that
        viewers that create temporary directories (e.g., lynx) will be
        able to access them.

Thu Aug 03 17:14:08 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * TODO: Allow multiple simultaneous differing contexts, probably
        each tied to a parent (terminal) process.

Tue Aug  1 10:48:05 EDT 2000 Kimmo Suominen <kim@tac.nyc.ny.us>

        * Makefile install rules should not look for generated files in
        the source tree -- this will happen to work when configuring and
        building inside the source tree but will fail when using an
        external build tree.  Fixed etc/Makefile.in.

Mon Jul 24 16:20:45 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * When Shantonu wrote the new, more portable dtimep.lex, he left
        out the #ifdef DSTXXX stuff for some reason.  Not a good idea, as
        that code is required for proper printing of numeric-offset
        timezones that have daylight saving time.  Without that code,
        -0700 during DST gets printed as MST instead of PDT.

        * Renamed DSTXXX as ADJUST_NUMERIC_ONLY_TZ_OFFSETS_WRT_DST and
        added an explanatory comment by its #definition.

        * Updated README.developers with the fact that zotnet/tws is going away.

Thu Jul 20 20:30:52 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Moved Kimmo's new "--with-hash-backup" to be output with the
        rest of the --with options in the configure --help output.  Also,
        people did not preserve my alphabetization of the --with options
        when they added new ones.  Re-alphabetized.

        * One more pass at README.developers now that it's clear that my
        previously-suggested one-line autoconf-file commit can cause
        unnecessary local makes and an out-of-sync stamp-h.in file, but
        would not cause problems for other people using the CVS files.

        * Ken Hornstein's SASL patch was not integrated properly with
        Ruud's new merged mts/sendmail code.  Kimmo has since fixed nmh so
        it compiles, but according to Ken, the SASL stuff still does not
        work.  Integrating a patch from him for this.

        * Last pass at README.developers -- Kimmo's 5-step commit was
        overkill.  You only need 3 steps, since configure.in is the only
        autoconf file with the RCS $Id keyword.

        * Applied Kurt J. Lidl <lidl@eng.us.uu.net>'s $MAILHOST patch:

            I have a small patch that would be nice to be included --
            basically, it allows the usage of the "MAILHOST" environment
            variable, without having to have HESIOD turned on.  I need
            this functionality for my environment, where we have identical
            /usr/local on all my machines (so I cannot just hardcode into
            the mts.conf file), and I have multiple POP mail servers for
            my users.

        Modified inc.man to reflect that along with "pophost:" and -host, 
        $MAILHOST can now activate POP mail inclusion as well.

        * Fixed warnings from diff on first-time install of nmh.  Also
        added 'echo's clarifying the etc file installation activities.

Tue Jul 18 19:36:59 EDT 2000 Kimmo Suominen <kim@tac.nyc.ny.us>

        * Added the answer to Dan's question in README.developers.

Mon Jul 17 19:10:36 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Clarified and made some corrections to Kimmo's README.developers
        changes (BTW, if anyone can explain why the RCS Ids are able to cause
        problems with the dependencies, please fill in the explanation --
        I never encountered a problem with the old single-commit method).

Sat Jul 15 23:13:49 EDT 2000 Kimmo Suominen <kim@tac.nyc.ny.us>

        * Add configure option --with-hash-backup so the backup prefix can
        be easily changed from "," to "#".

        * Simplified sbr/Makefile.in so that it works with any make.

        * Use mkstemp in sbr/lock_file.c.

        * Commits of autoconf-related files apparently can't all be done
        in one shot due to RCS Ids changing when committing -- updated
        README.developers.

Tue Jul 11 14:18:01 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Clarified post.man and send.man for those not completely up on
        SASL terminology.  "SASL encryption layers are not supported for
        SMTP" means that encryption is supported for the authentication
        but not for the subsequent data stream.

Sat Jul  8 01:36:19 EDT 2000 Kimmo Suominen <kim@tac.nyc.ny.us>

        * Applied Ken Hornstein <kenh@cmf.nrl.navy.mil>'s patches
        implementing SASL support for POP3 and SMTP.  If nmh is compiled
        with SASL support, using the -sasl switch on the inc, msgchk,
        post, and send commands will enable authentication encryption for
        SMTP, and both authentication and data stream encryption for POP3.

Sat Jun 10 18:37:59 CEST 2000 Ruud de Rooij <ruud@ruud.org>

        * Merged mts/sendmail functionality into mts/smtp; switching between
        smtp and sendmail delivery method is now controlled by mts.conf.

        * If tsort cannot deal with loops, in addition to defining tsort as
        cat, also define lorder as echo.
        
        * Removed uip/popi.c from list of sources.

Thu Jun 08 19:36:57 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * New dtimep.lex didn't parse day names properly.  Fixed.  Also
        clarified ambiguous comments preceding day_map[] array (from old
        dtimep.lex) that probably led to the erroneous cp++ being added.

Wed Jun  7 20:52:33 CEST 2000 Ruud de Rooij <ruud@ruud.org>

        * Added one more mkstemp invocation to uip/spost.c (which was in a
        #if 0 block).

        * Applied patch from Peter Maydell to clean up permissions handling
        and error handling in uip/inc.c.

Mon Jun  5 22:10:07 CEST 2000 Ruud de Rooij <ruud@ruud.org>

        * Use cat instead of tsort if tsort cannot deal with loops in its
        input (which is the case for tsort from GNU textutils).

Mon Jun  5 21:14:36 CEST 2000 Ruud de Rooij <ruud@ruud.org>

        * If lockfile is present, and its dotlockfile program is setgid,
        inc does not need to be setgid.

Sun Jun  4 21:35:40 CEST 2000 Ruud de Rooij <ruud@ruud.org>

        * Added autoconf test for Miquel van Smoorenburg's liblockfile
        library, as found on Debian systems.

        * Added liblockfile support to sbr/lock_file.c.
        
Wed May 31 7:19:30 2000 Shantonu Sen <ssen@mit.edu>
        
        * Fixed up dtimep.lex a bit. Added back memory options for AIX to
        increase available memory.  Took out %option noyywrap, which
        wasn't understood by AT&T lex, as well as the -i
        case-insensitivity flag.

Wed May 31 07:40:45 2000 Doug Morris <doug@mhost.com>

        * Added a lint target to the Makefiles and a check in autoconf
        to determine whether lint or lclint exists on the system. 

Fri May 30 19:21:48 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * etc/Makefile.in was incorrectly installing mts.conf.in and
        sendfiles.in -- fixed.  Generated sendfiles script was not a
        dependency of the `all' target, and was incorrectly included in
        the distribution.  Changed the suffix for the backed-up previous
        versions of the etc files from the ambiguous .old to .prev.  Added
        call to diff -- only keep the .prev files around if different from
        the newly-installed versions (intentionally didn't redirect output
        to /dev/null so you'll notice when your changed versions are
        getting moved aside).

        * INSTALL never documented the etc/*.old thing.  Documented the
        new etc/*.prev thing (including a note to watch for diff output).

        * Applied Alec Wolman <wolman@cs.washington.edu>'s dropsbr.c patch:

            In the map_write routine, a call is made to map_open and this
            call is supposed to set the "clear" variable to 0 or 1,
            depending on whether the map file is empty or not.  In
            mh6.8.3, this worked because map_open would set "clear" by
            calling the mbx_Xopen routine.  In nmh, the code for mbx_Xopen
            was merged into mbx_open, but the interface for mbx_open
            doesn't support the clear variable, so that functionality was
            lost.  The map_open interface still contains "int *clear" in
            the prototype, but never sets it.

            My patch eliminates "clear" from the map_open interface (I
            checked to make sure that map_write is the only client of
            map_open).  Furthermore, my patch also sets the "clear"
            variable properly at the beginning of map_write by calling
            fstat().  This eliminates the bug in that the value of "clear"
            being used later in the routine was just stack garbage.

            Having a bad value of clear causes this next bug to be
            triggered: The fp file pointer was being opened with fdopen,
            but in two of the three switch cases it wasn't being closed.
            In certain cases, this was causing packf to run out of file
            descriptors if you attempted to pack a large folder.

Mon May 29 7:48:15 2000 Shantonu Sen <ssen@mit.edu>

        * Moved the date parsing routines from zotnet/tws to sbr/ (and
        tws.h to h/). Updated all source files to reflect to new location
        of tws.h.

        * Rewrote dparsetime (in dtimep.lex -> dtimep.c) to replace the
        old zotnet/tws/dtimep.c, dtimep.lex, lexstring.c, lexedit.c, and
        dtimep.c-lexed. It should now work with flex (although untested
        with lex), and requires no sed-ing. For now, I have the lexed
        version in the distribution, so that end-users don't need to worry
        about running it through flex/lex. I have not added back support
        for guessing the time zone when it's not specified.
        
Sun May 28 17:44:15 CEST 2000 Ruud de Rooij <ruud@ruud.org>

        * Added autoconf check for getutent().

        * Changed uip/rcvtty.c and uip/slocal.c to use getutent() and
        friends.  Since I can only check on Linux, please check if
        this works on other systems.

Sun May 28 14:58:49 CEST 2000 Ruud de Rooij <ruud@ruud.org>

        * Applied patch from Peter Maydell to uip/scansbr.c for more
        checks for write failures.

        * Unlink temporary file properly in uip/rcvtty.c.

        * Moved viamail from bindir to libdir.

        * Changed sendfiles into sendfiles.in, so that path to viamail
        is patched in.

        * Added gzip support to sendfiles.

        * Added References header to replcomps and replgroupcomps.

Sun May 28 14:39:31 CEST 2000 Ruud de Rooij <ruud@ruud.org>

        * Fixed m_getfld bug which caused segmentation faults when
        incorporating messages which ended in multiple linefeeds crossing
        a buffer boundary.

Fri May 26 13:21:59 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * msh has been unable to show MIME messages ever since 1.0.  Alec
        Wolman <wolman@cs.washington.edu> tracked down the problem to the
        -show flag being passed to mhshow.  mhshow is equivalent to the
        old mhn -show, so we don't need the -show anymore.  Removed it.

Fri May 12 02:51:21 2000 Shantonu Sen <ssen@mit.edu>

        * zotnet/bboards is not longer built by default. Goal is to move
        the assorted functions in zotnet into sbr or some more logical
        place.

        * Moved zotnet/mf to sbr, and changed mf.h references accordingly,
        as well as Makefiles.
        
Thu May 11 02:21:34 2000 Shantonu Sen <ssen@mit.edu>

        * Simplified sbr/Makefile.in so that both SRCS and OBJS aren't
        seperately and redundantly defined, but so that OBJS is a
        pattern-substituted version of SRCS with suffix .c -> .o. This
        should make maintainability easier.

        * Added section to MACHINES indicating what platforms nmh is known
        to compile and work on, just to give users peace of mind, or
        something. This is by no means complete or exhaustive, so add
        whatever you know works.
        
Tue May 09 20:38:04 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Alphabetized Shantonu's $pop_kinds output on configure's "pop is
        enabled" line.  If POP3 is the only kind of POP enabled, say so,
        rather than just saying "yes" (which is ambiguous).

        * Fixed four warnings in Shantonu's new getpass.c.  Needed to
        #include <stdlib.h> for calloc(), <unistd.h> for ttyname(), and
        "h/mh.h" for adios().  Also changed ch from char to int to get rid
        of "comparison is always 1 due to limited range of data type" on EOF.

        * Added steps to README.developers saying to change the version
        number to X.Y.Z+dev.  Did a little rearranging and changed the FTP
        dir from /home/ftp to /var/ftp to reflect Doug's new machine.

        * Changed configure.in to use gcc -Wall even without
        --enable-debug, to prevent developers compiling optimized from
        introducing warnings, and to give end-users a warm, fuzzy feeling
        as they (hopefully) see no warnings come out (except perhaps on
        the lex output file) even with -Wall.

        * Renamed getpass() to nmh_getpass() since the prototype for
        getpass() varies from OS to OS, and we want to _always_ use our
        version of the function.  Fixed all the callers to use
        nmh_getpass() and added it to prototypes.h.  Semi-arbitrarily
        upped MAX_PASSWORD_LEN from 128 to 256.  buf was being calloc()'d
        and the memory leaked -- should have just been declared as static
        char array.  Prepended "Portions of this code are" to the
        copyright message, as this version has been changed significantly
        from the BSD version.

        * Added "nmh-local functions to use in preference to OS versions"
        section to README.developers (currently just says to use
        nmh_getpass() instead of system getpass()).

        * Prepended "Portions of this code are" to the copyright message
        in ruserpass.c also.

        * Added mts.conf.5 page per Neil W Rickert <rickert+nmh@cs.niu.edu>'s
        report:
        
            This happens on solaris:

                     % man mts.conf
                     windex entry incorrect:  mts.conf(5) not found.
                     No manual entry for mts.conf.

            It is fixed by

                     % echo ".so man5/mh-tailor.5" > mts.conf.5

            done in the man5 directory.  We need to add 'mts.conf.5' as a
            reference sourcing mh-tailor.5.
        
Mon May 08 23:51:55 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Doug informed me that the way I had restored the "lost" version
        histories was wrong, because `cvs checkout's of old versions of
        nmh wouldn't work properly.  It occurs to me that this could be
        fixed by simply deleting those tags in the new-location *,v files,
        but oh well.  I'm putting everything back to the way Doug
        originally had it.  To get the old version history for a file that
        used to be in the top directory, you'll need to "blindly" do a
        `cvs log' there (even though you won't have a local copy of the
        file in that directory).  `cvs diff' will no longer be able to
        diff pre-move versions vs. post-move versions -- you'll have to do
        a lot of manual gyrations with `cvs checkout' and then use `diff'.

        * I had alphabetized the --configure options in the --help output
        awhile back, but Shantonu added --enable-apop just under
        --enable-pop.  Put it in alphabetical order and clarified what
        --enable-apop does vs. --enable-pop and --with-krb4.  Also changed
        --with-mts help line from "mail transport agent" to "mail
        transport agent/service" so the 's' in "mts" doesn't seem to come
        out of nowhere.

        * Added two steps to "releasing nmh" in README.developers.  After
        making the tarball, it's a good idea to diff the tree vs. the CVS
        tree to make sure no files got left out, and then to chown the
        files so that they're owned by root, preventing a Trojaning attack
        by a malicious remote user with a UID matching yours.

        * Changed DIFFERENCES to say that RPOP is not currently supported
        rather than implying it by saying that APOP, KPOP, and POP[3] are.

Sun May 07 18:16:43 2000 Shantonu Sen <ssen@mit.edu>

        * Imported NetBSD version of getpass() and made extensive
        revisions for compatibility with programs that pipe the password
        to stdin, such as exmh.

        * Removed tests for system ruserpass() which sometimes gave
        phantom positive results. Also, bext to use internal functions if
        we ever want to change .netrc format to something else, or access
        other files.

Sat May 06 08:28:09 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Restored lost version histories for those moved files by doing a
        manual `mv' in the CVSROOT on mhost.  CVS badly needs a `cvs mv'
        command so that you can move files (without having physical access
        to the CVSROOT) without losing versioning.  Put MACHINES back at
        the top level as it needs to be read before building.  Fixed DIST
        variable in {.,docs}/Makefile.in to reflect that and to add
        missing entry for "INSTALL" file.

Sat May 06 13:13:07 2000 Doug Morris <doug@mhost.com>

        * Re-cleaned up nmh documentation (by moving things to docs
        subdir) and modified Makefile & configure.in to handle the change.

Mon Apr 17 21:28:40 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Scott Blachowicz pointed out that the configure --help output
        for --enable-masquerade was misleading.  Clarified.
        
Mon Apr 17 19:01:00 2000 Shantonu Sen <ssen@mit.edu>

        * APOP support can be compiled in to inc and msgchk using
        --enable-apop.

        * To access an APOP host, specify -apop on the command line
        along with any -host or -user option.

Fri Apr 14 23:10:44 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Upped the version number to 1.0.4+dev until the next nmh release.

        * Added a "releasing nmh" section to README.developers, while the
        process was fresh in my mind.
        
Fri Apr 14 18:21:34 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Added new files README.developers, ChangeLog_MH-3_to_MH-6.6, and
        ChangeLog_MH-6.7.0_to_MH-6.8.4.html to DIST target in Makefile.in.
        
        * Released nmh-1.0.4.

Tue Apr 11 21:37:03 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Applied Brian Campbell <bacam@tardis.ed.ac.uk>'s mhn.defaults.sh
        patch:

            It appears that there shouldn't be quotes around the %s in the
            iso-8859-1 charset entry; xterm passes the remaining arguments
            to the program, quoting them means that xterm thinks they're
            part of the program's name.

        This %s isn't the same as the "Insert content subtype" one from
        mhshow-show-* -- it doesn't come from MIME headers and is safe not
        to quote.

Sun Apr 09 13:03:59 2000 Doug Morris <doug@mhost.com>

        * added check in fmt_compile() to handle a single-character
        format string. fmt_compile() depends on having an array of
        format characters with an empty item at the end. A
        single-character format would cause programs using this
        function to segfault because the algorithm used to decide on
        the length of the array mistakenly created a single-item array
        when the format string was one character. This eventually
        caused problems when the program attempted to test item+1
        in the array.

Thu Apr 06 21:53:50 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Richard Coleman threw out a lot of old MH-specific files in nmh.
        Much of the stuff, indeed, is not worth saving, but there are
        nuggets that are very worthwhile, and should probably be added
        back in.  Most important, IMHO, are the MH change logs, as they
        can help answer questions like "Why is this code like this?" or
        "How long has this been broken?" or "What was this ever used for?"

        I've added a new file to the nmh tree called
        ChangeLog_MH-3_to_MH-6.6.  It's cobbled together from the
        mh-6.8.4/papers/mh*/MHCHANGES files.  I've re-ordered the entries
        to go from newest at the top to oldest at the bottom to match the
        ChangeLog convention.  Unfortunately there are no change logs for
        versions of MH prior to 3 in the MH tar files available at
        <ftp://ftp.ics.uci.edu/pub/mh>.  Also, it appears to me that there
        are MH-6.6 changes that aren't documented in the logs.

        I've also added ChangeLog_MH-6.7.0_to_MH-6.8.4.html.  This is
        based on mh-6.8.4/papers/changes/mh-changes.ms.  The nroff format
        and its "catman"-type output are a pain to deal with, but I was
        loath to throw away the formatting, so I converted the file to
        HTML.  The only actual markup in the body are the "<B>" and "<U>"
        tags, and "&lt;" and "&gt;" instead of '<' and '>', so it's quite
        doable to view the file in plain ASCII mode as well.  Note that
        some of the changes this file documents as having been made in
        MH-6.8.4 may not be present in nmh -- Richard started with 6.8.3
        and later put in certain 6.8.4 stuff.
        
Wed Apr 05 21:09:28 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Applied Eric Schnoebelen <eric@cirr.com>'s mhshowsbr.c patch
        fixing apparent bugs in Dan Winship's new security quoting code:
        
            Since upgrading, I've been getting the following errors
            while attempting to process some MIME messages:

                (1) Syntax error: Unterminated quoted string
                    exit 2
        
            and:

                (2) line 1/10 (END)Segmentation fault (core dumped)

            (2) appears to be due to the testing of an unset pointer in
            mhshowsbr.c:show_multi_aux().  (1) appears to be caused by
            mis-quoting a filename being handed to the shell in
            mhshowsbr.c:show_content_aux().

            Resolving the pointer reference issue in
            mhshowsbr.c:show_multi_aux() turned up a similar mis-quoting
            problem in the routine.

Tue Mar 28 16:17:39 2000 Doug Morris <doug@mhost.com>

        * Applied Todd.Miller@courtesan.com's patch to dropsbr.c to
        prevent core dumping on packf. Here's the note from his message:

            Since sizeof(buffer) == sizeof(tmpbuffer) packf will dump
            core on a file w/o a From line with a line >= BUFSIZ.
            I noticed this because I had a junk file in my mail
            spool somehow.

Fri Mar 17 11:59:33 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * wesley.craig@umich.edu did not document his previous KPOP patch,
        so I did so, and asked him to check what I wrote.  Unfortunately
        he didn't notice my misunderstanding of his patch.  I wrote that
        if you #define POPSERVICE "kpop", inc and msgchk will use KPOP
        exclusively, but if you leave it as "pop3", you can use Wesley's
        new -kpop switch on a given invocation.  Instead, however, -kpop
        turned out to be necessary on every invocation, and a KPOP user
        complained.  Applied Wesley's new patch, which makes things work
        like I thought his original patch did.  After that, did one more
        clarifying pass to the documentation in inc.man and msgchk.man.

Wed Mar 15 18:45:45 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * When I fixed the long-standing makedir() bugs in January, I had
        the code call strtoul(..., 0), which I believed to be safe as all
        modes specified as ASCII constants in the nmh code started with a
        leading zero (signifying octal), which I did as it would work if
        internal constants were ever changed to hex.  Unfortunately I was
        unaware of the "Folder-Protect:" .mh_profile entry, which
        mh-profile.man documents as an octal-only constant, with no
        leading zero required.  I've changed the strtoul() call to an
        atooi() call and removed the misleading leading zeroes on the
        ASCII octal constants in the code and man pages.  Also changed the
        "Folder-Protect:" example in the man page to something more
        interesting than a duplication of the default.

        * When I added my --enable-masquerade option, you'll note that I
        didn't make it --enable-nmh-masquerade.  I find the --enable-nmh-*
        options too wordy and I'm not sure why Richard went that route.
        I've renamed them to just --enable-*, but the old versions will
        still work as well (they just aren't advertised).

        * Added a line to the "nmh configuration" output saying whether
        POP is enabled.

        * Added a new README.developers file.  From the file:

            This file is intended to provide a few tips for anyone doing
            development on nmh.  Developers who learn things "the hard
            way" about the nmh codebase (as opposed to local info best
            encoded in a comment) are encouraged to share their wisdom
            here.

        Currently the topics are "autoconf files" and "directory structure".

Tue Mar 14 12:41:48 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Applied, after some finessing,
        Simon Burge <simonb@thistledown.com.au>'s --with-smtpservers patch:

            Here's a patch that allows you to add

                    --with-smtpservers=<some.host.name>

            to the ./configure command line to set the "servers: " line in
            etc/mts.conf.  Around here, we use "mailhost" so that all
            machines in the current domain just talk to a central machine
            and nothing else runs an MTA.  Now, I can use

                    --with-smtpservers=mailhost

            instead of having to remember to fix this by hand (and often
            forgetting to do so!).

        * Inspired by Simon's patch, added an --enable-masquerade option
        to configure.  It will set the "masquerade:" line of mts.conf.
        You may specify a subset of the three types of masquerading, like
        --enable-masquerade="draft_from mmailid", or leave off explicit
        arguments to enable all three types.

        * Alphabetized the --enable and --with options in configure.in and
        INSTALL and added documentation of the two new options to the latter.

        * Added new dependency for mts.conf: Makefile.  If this isn't
        done, then when you reconfigure nmh with new values for
        --enable-masquerade or --with-smtpservers, you'll fail to get an
        updated copy of mts.conf.

        * Applied Simon Burge <simonb@thistledown.com.au>'s dtimep.lex patch:

            It seems that some MUA's didn't handle y2k very well - ELM
            seems to be one of them, and Ultrix's DXmail (based on MH!).
            I've got a few emails this month that look like:

                    575   Jan 00  Xxxxxx Xxxx       3603  ...
            and
                     22+  Jan 00  Xxx Xxxxx         1771  ...

            The first has "15 Jan 100" as the date and the second has 
            "19 Jan 00" as the date.  The following works around this so 
            that scan, show, sortm, etc work ok.

        I put Simon's patch under the control of a new #define called
        FIX_NON_Y2K_COMPLIANT_MUA_DATES.  There's some commentary in
        acconfig.h about when you might not want to #define it.

        * Created new dtimep.c-lexed with Simon's change using dtimep.lex
        lexed on Solaris 2.6.  Added missing dependency in
        zotnet/tws/Makefile.in for dtimep.c: dtimep.c-lexed.

        * Added scan.MMDDYY and scan.YYYYMMDD format files.

Mon Mar 13 21:32:00 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Applied Sullivan N. Beck <sbeck@cise.ufl.edu>'s mhshow-suffix patch:

            With the patch below, you can add lines like:

                mhshow-suffix-application/msword: .doc
                mhshow-suffix-application/PostScript: .ps

            to the mhn.defaults file to append the given suffix to a
            scratch file.  This allows applications which require a
            certain suffix to run properly.

        * Removed -force_html from lynx entry in mhn.defaults.sh (I
        believe older versions of lynx lack that option) and added
        "mhshow-suffix-text/html: .html".
                
        * Modified username_extension masquerading to only use the
        extended address on generated [Resent-]From: lines and SMTP
        envelope From:.  With Neil's original implementation, nmh's global
        idea of the username was changed, which would result in inc lying
        and saying you had no new mail because it was looking for a
        mailbox called, for instance, "dan-nmh" (where username was "dan"
        and $USERNAME_EXTENSION was "-nmh").
                
        * Applied Simon Burge <simonb@thistledown.com.au>'s dtime.c patch:
        
            There's a wrap-around problem that affects the implementation
            of Zeller's congruence in dtime.c.  This causes the day-of-week
            calculations to fail for dates after Feb 29, 2000 (probably up
            until some year far in the future).

Mon Mar 06 12:20:20 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Applied Neil W Rickert <rickert+nmh@cs.niu.edu>'s msh.c patch:

            I finally tracked down the problem in msh that was causing
            errors whenever I tried to examine a 'mmdf' style mailbox.

            It turns out that not enough memory was being allocated with
            calloc(), causing memory pointers to be overwritten and
            corrupted.
                
Fri Mar 03 16:07:33 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Changed the new "plussed_user" option to mts.conf's
        "masquerade:" to "username_extension" after getting feedback from
        qmail users, who use '-' as a separator rather than '+'.  Removed
        checking of $USERPLUS variable.  Now check $USERNAME_EXTENSION,
        which needs to include the appropriate separator for your MTA
        ('-', '+', or whatever) as its first character.
                
Thu Mar 02 23:04:30 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Added a new "boolean" type to mh.h and TRUE and FALSE constants.
                
        * Added a note to DIFFERENCES stating that it's out-of-date
        (Richard was the last one to update it) and that we should
        consider only documenting incompatibilities with MH there.

        * Implemented (and documented) a third kind of username
        masquerading: "plussed user" masquerading.  This one was suggested
        by Neil Rickert <rickert+nmh@cs.niu.edu>.  It's based on sendmail's
        "plussed user" feature, where mail sent to <user>+<string> will be
        delivered to <user>.  When it's enabled, it's controlled by the
        $USERPLUS environment variable.  How is it enabled?  Well, that
        leads me to:

        * Renamed the "mmailid:" setting in mts.conf to "masquerade:", and
        changed it so that rather than being a boolean, it can be set to
        any combination of the three values "draft_from", "mmailid", and
        "plussed_user".  Thus it is now possible to enable the three types
        of masquerading individually.

        * Fixed a bug with "mmailid" masquerading (dating back to MH?)
        where if it was turned on, ','s would no longer be considered
        GECOS field delimiters.
        
Wed Mar 01 23:30:50 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Changed the GECOS-field '&' translation behavior to be
        controlled by the BSD42 #define rather than GCOS_HACK, since it's
        apparently always appropriate on OSes where BSD42 is #defined, and
        never appropriate on any other OSes.  Thanks to Kimmo Suominen for
        responding to my "What is this code here for?" comment in mts.c
        and explaining the feature.
        
Mon Feb 28 21:50:29 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Upped the version number to 1.0.3+dev (ideally this should be
        done by whoever makes a release tar file, immediately after doing
        so).
        
        * Applied Paul Fox <pgf-spam@foxharp.boston.ma.us>'s scansbr.c
        patch, posted to comp.mail.mh, which he says prevents loss of mail
        when inc'ing into a full filesystem.

        * Changed "echo > stamp-h.in" in Makefile.in to "date > stamp-h.in"
        so that stamp-h.in will be different each time configure.in and
        related files are changed, making it easier to check it in (which
        is necessary to prevent unnecessary autoconf calls).

        * My declaration of initgroups() in slocal.c to eliminate the "no
        prototype" warning wasn't portable (FreeBSD 3.[23] choked).  Now
        use AC_EGREP_HEADER to see where initgroups() is declared, if
        anywhere.

Sun Feb 20 12:17:15 2000 Ruud de Rooij <ruud@ruud.org>

        * Fix security hole in mhshowsbr.c which allowed untrusted shell
          code to be executed.
        
        * Released nmh 1.0.3.

Thu Feb 10 10:54:36 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Oops.  %-escapes on mhstore lines in mhn.defaults.sh should not
        be surrounded by single quotes, as a shell is not spawned when
        just saving files, and the filenames will end up with literal
        quotes embedded in them.

Fri Feb 04 12:29:12 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Whoever originally added the -help switch to all the commands
        got too cute and had the option itself print out as "-(help)" in
        the -help output.  One theory is that they were making reference
        to the fact that clearly you know about the -help option since
        you're currently looking at its output.  I think it's a bad idea
        to overload the meaning of the parentheses, however -- they're
        supposed to indicate what abbreviated prefix of the switch you're
        allowed to specify.

        The other theory is that because you can say something like
        "mhstore -" and get "mhstore: - ambiguous.  It matches" followed
        by the same list of switches you get with -help, they were saying
        you can "sorta" abbreviate "-help" as "-".  You don't get the
        "Usage:" string, though, so it's not really the same thing.

Thu Feb 03 17:52:01 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Applied wesley.craig@umich.edu's KPOP patches.  According to him:

              The following patch fixes a problem with requesting a
              service key for a machine that has multiple 'A' records.  It
              also makes "-kpop" a command line option, for users who
              would like to use both "kpop" and "pop".

        Did no testing of the new features, as I don't have access to a
        KPOP server.

        * Modified inc.man and msgchk.man to document Wesley's new -kpop.

        * Modified INSTALL and config.h.in to reflect the new -kpop feature.

Fri Jan 28 17:39:24 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * All %-escapes in mhn.defaults that actually expand to something
        should be surrounded by single quotes.  Added quotes to the ones
        in mhn.defaults.sh that were missing them.

        * Added check for lynx to write mhshow-show-text/html line in
        mhn.defaults.sh.

Thu Jan 27 12:22:25 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * makedir() had multiple bugs dating back to MH.  An octal
        constant was apparently being interpreted as decimal, resulting in
        directories with no user read or execute permissions, making
        nested directory creation fail.  And there wasn't even an
        _attempt_ to set desired permissions (e.g. from "Folder-Protect:"
        in .mh_profile) on the outer directories of a nested directory.

        * A second `make install' would always fail because the check for
        whether mh_profile.5 existed was written incorrectly.
        
Wed Jan 26 02:22:00 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Added documentation on both types of masquerading to post's man
        page.

Tue Jan 25 22:58:12 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Doug's portability fix of my setgid inc autodetection had a
        caching bug -- if you re-ran configure, uip/Makefile would be
        corrupted, and installation would bomb out on OSes where inc needs
        to be setgid.

        * Implemented a new kind of email address masquerading.  Usually,
        when a user writes a custom "From:" header in a draft, nmh uses it
        rather than generating one.  However, the user's true address is
        used in the SMTP envelope "From:" and is revealed in the "Sender:"
        header.  Now, when mmailid is set to non-zero, the envelope
        "From:" uses the address specified in the draft "From:" header,
        and there is no "Sender:" header.  This is useful when sending on
        behalf of a remote POP3 account or when remote mail robots
        incorrectly use the envelope "From:" in preference to the body
        "From:".  This processing has only been implemented for post, not
        for the undocumented spost (which was already missing some "From:"
        processing that post has).

Mon Jan 24 22:26:06 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Got rid of the rest of the gcc -Wall warnings that I didn't have
        time for on 1999-07-15 (and, it would seem, some new ones people
        introduced since then).  The primary ones were the warnings that
        default prototypes were being used for [v]snprintf() and
        str[n]casecmp().  As of right now, there are _no_ compilation
        warnings except on dtimep.c-lexed (at least under AIX 4.1.5 and
        Solaris 2.6).

Sun Jan 2 23:42:18 2000 Ruud de Rooij <ruud@ruud.org>

        * Move mhtest from bindir to libdir.

        * Move sendfiles from libdir to bindir.

        * Updated sendfiles manpage to reflect this change.

        * Added documentation for -build and -file switches to repl and 
          forw manpages (patch from Peter Maydell).

        * Fixed interaction between specifying -cc in profile and -group on 
          command-line.

Tue Nov 1 13:48:10 1999 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Changed the version number from 1.0.3 to 1.0.2+dev.  There was
        not unanimous support for my proposed even/odd release/developer
        version number dichotomy.  1.0.2+dev implies release 1.0.2 plus
        some development.

Fri Oct 29 13:42:51 1999 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Upped the version number to 1.0.3.  If we don't do this, then
        when people report bugs against 1.0.2, we won't know "which" 1.0.2
        they're talking about (since the development source is publically
        available via CVS).  I think the Linux kernel version numbers are
        a good model, so the next time we roll a tarball, it should be
        version 1.0.4 (or higher -- anyhow, an even-numbered version).

Fri Oct 29 06:41:08 1999 Doug Morris <doug@mhost.com>

        * Released nmh-1.0.2.

Tue Oct 26 22:57:00 1999 Doug Morris <doug@mhost.com>
        
        * Added check for whether "libtool" is in fact gnu libtool. If
        it is, it is not used. This is the wrong behavior. If vendor
        XYZ later on decides to create yet another libtool, we'll be
        caught again. This works for now.

        * Minor updates to MACHINES refering to Mac OS X.

Thu Oct 21 20:45:37 1999 Doug Morris <doug@mhost.com>

        * Added check for "libtool" (a ranlib type tool for Mac OS X)
        and modified Makefiles so that nmh will build under Mac OS X.

Sun Oct 17 08:28:56 1999 Ruud de Rooij <ruud@ruud.org>

        * Changed repl defaults to partly revert to MH behaviour,
          "-cc all" is now only implied with -group.

        * The replcomps template includes cc: header again (as in MH).

        * Updated repl man page to reflect these changes.

Sat Oct 16 02:57:47 1999 Doug Morris <doug@mhost.com>

        * Tweaked configure to handle Solaris and SunOS after the BIND
        changes. Both need more cleanup.

Sat Oct 16 00:17:36 1999 Doug Morris <doug@mhost.com>

        * Removed BIND define and replaced it with a check for
        gethostbyname (to determine if the host is DNS aware) and a
        check for sethostent. This appears to be the right thing to
        do, but there is no explanation of the reasoning behind the
        BIND define in the code and it appears to have been used for
        multiple purposes. 

Wed Oct 13 15:53:53 1999 Doug Morris <doug@mhost.com>

        * Updated manpages Makefile to link mh-profile.5 to
        mh_profile.5 after installation. Suggestion from Richard Cohen
        <richard@jubjub.demon.co.uk>.

        * Modified configure.in to check for _IO_write_ptr and libio.h
        to determine whether to define LINUX_STDIO instead of using 
        config.guess.

Mon Oct 4 15:22:46 1999 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Added '-L' to the calls of 'ls' in configure.in -- I have seen
        multiple machines in the past where the mail spool was a symlink
        to a directory on another device with more free space.

Fri Oct 1 22:36:56 1999 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Fixed a portability problem in Doug's fix of a portability
        problem in my MAILGROUP autoconf support ('ls -l' vs. 'ls -lg'). 

Sat Sep 25 18:40:43 1999 Ruud de Rooij <ruud@ruud.org>

        * Added config.sub and config.guess to the list of files to be
        distributed.

        * Fixed bug in sbr/fmt_scan.c where an extra newline would be
        added if a list of addresses was split over several header lines.

        * In mts/smtp/smtp.c, undefine strlen and strcpy if they are
        macros, regardless of platform.

        * Allow q to quit mhshow, and n to skip to next part.  Patch from
        Kimmo Suominen <kim@tac.nyc.ny.us>.

        * Modified mhstore to recognize attachments created by sendfiles
        with x-conversions=gzip.

Mon Sep 13 21:20:10 1999 Doug Morris <doug@mhost.com>

        * added explicit cast to long from time_t for tclock in
        post.c.

        * Commented out #ifdefs for <sys/ioctl.h> in termsbr.c since
        it's needed for ioctl() anyway. This prevents a warning about
        implicit definition of ioctl().

        * Moved guesses performed by AC_CANONICAL_SYSTEM back into the
        "User Configuration" section of config.h (moved @TOP@ in
        acconfig.h) so they're easier to find, should someone actually
        want to mess with them.

Sun Sep 12 15:50:34 1999 Doug Morris <doug@mhost.com>

        * updated Makefile.in so it recognized COMPLETION-TCSH and
        COMPLETION-ZSH (only used in make nmhdist). 

        * added prototype for ruserpas to <h/prototypes.h>. Fixes
        warnings in mhparse.c and mhbuildsbr.c.

        * added include checks for <time.h> and <sys/time.h> to
        prevent warnings in fmt_compile.c, fmt_scan.c, lock_file.c,
        sendsbr.c, mhbuildsbr.c, mhcachesbr.c, picksbr.c, and post.c.

        * added include for <zotnet/mts/mts.h> to ali.c, scan.c, ap.c,
        rcvdist.c, rcvstore.c, rcvtty.c, and spost.c to remove
        warnings about implicit definition of mts_init().

        * added <grps.h> to slocal.c to prevent warnings about
        function initgroups.

        * added <h/signals.h> to prevent warning about missing SIGNAL
        function.

        * added function prototypes to smtp.c, whatnowproc.c,
        mhbuildsbr.c, mhparse.c, mshcmds.c, show.c, whatnow.c, mhl.c
        to fix warnings.

        * explicitly declared mbx_style in mshcmds.c and lused in
        fmtdump.c as type static int instead of just static to
        prevent warnings.
        
        * various code cleanups to prevent ambiguous statements
        (brackets for if/thens and parens for complicated if
        statements).


Sun Sep 12 09:19:27 1999 Doug Morris <doug@mhost.com>

        * commented out _cleanup() in mf.c because it's the only
        location in all of the source code where it exists. It was
        preventing compilation on at least linux.

        * Added check for <db1/ndbm.h> which is the new location where
        linux systems appear to be stuffing this header file.

Thu Sep 09 23:15:49 1999 Doug Morris <doug@mhost.com>

        * fixed varous mkstmep bugs introduced in 1.0.1 by me. Whups!

        * added mh_profile SEGV patch from Richard Cohen
        <richard@jubjub.demon.co.uk> that prevents crashing when
        mh_profile doesn't end in a newline. A similar patch was
        previously sent in by Andrew Bettison <andrewb@zip.com.au>.

        * fixed bug in associated with MAILGROUP #define (group "mail"
        is not universal) -- hard to believe, but true.

Tue Sep 7 16:47:03 1999 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Renamed ZSH.COMPLETION to COMPLETION-ZSH and added COMPLETION-TCSH.

Tue Aug 17 16:06:29 1999 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Automated #define of MAILGROUP and installation of inc as setgid mail
        when the mail spool directory isn't world-writable.

Thu Jul 15 18:37:07 1999 Dan Harkless <dan-nmh@dilvish.speed.net>

        * slocal -debug used to leave a file in /tmp for each message
        processed.  Very bad for folks with slocal -debug in their .forward!

        * Got rid of a ton of compilation warnings.  Most were "junk"
        warnings due to the use of gcc -Wall (without -Wno-parentheses),
        but a few represented real bugs.  There remain many warnings to be
        tackled that are due to missing function prototypes (e.g. snprintf()).

        * Default rcvdistcomps no longer puts a copy of all outgoing
        messages in outbox.  Added an rcvdistcomps.outbox that does.

Sat Jun 09 12:22:47 1999 Doug Morris <doug@mhost.com>

        * Updated configure to check for mkstemp (available on OpenBSD) and 
        substitute it for mktemp if available. 

Thu May 13 16:40:19 1999  Doug Morris <doug@mhost.com>

        * Added config.sub and config.guess and updated acconfig.h and
        configure.in to automatically detect system type and set the
        proper #defines.

Wed May 12 23:41:33 1999  Dan Winship  <danw@mit.edu>

        * Released nmh-1.0.1.

Fri May  7 17:18:28 1999  Dan Winship  <danw@mit.edu>

        * Fixed flist to properly deal with relative folder names.
        Problem noted by Jerry Peek <jpeek@jpeek.com>.

        * Fixed --with-krb4 to work with original Kerberos 4 libraries as
        well as the Kerberos 5 compat libraries. Based on a patch from
        Assar Westerlund <assar@sics.se>.

        * Added a check in configure.in to test if modf is in libc and
        link with libm if not. This is needed by at least Digital UNIX. 
        Problem pointed out by Kevin Oberman <oberman@es.net>.

        * Fix a bug from the "mhn -show" to "mhshow" renaming that
        made the "list" command in whatnow not work for some users.
        From Ruud de Rooij <r.c.m.derooij@twi.tudelft.nl>.

        * Replaced "extern int errno" with "#include <errno.h>" in a
        number of files. Suggested by Stephen Wilson Bailey
        <swb@nconnect.net>.

        * Fixed a problem in how "packf -mbox" translated "Return-Path:"
        lines. From Kimmo Suominen <kim@tac.nyc.ny.us>.

        * Fixed a segmentation fault in inc. Patch originally from Ruud de
        Rooij <r.c.m.derooij@twi.tudelft.nl>.

        * Allow display of 8bit encoded messages. From Kimmo Suominen
        <kim@tac.nyc.ny.us>.

        * Fixed repl to not add line breaks in the middle of long
        addresses when building a reply. From Ruud de Rooij
        <r.c.m.derooij@twi.tudelft.nl>.

        * Added -library switch to spost so it can parse user aliases like
        post does. From Ruud de Rooij <r.c.m.derooij@twi.tudelft.nl>.

        * Changed configure.in's check for sigsetjmp to properly deal
        with systems like Linux where it is a macro. From
        <elleron@servtech.com>.

        * Fixed a bug in whatnow that could cause it to sometimes exit
        without prompting the user. Based on a patch by Richard Geiger
        <rmg@netapp.com>.

        * Added code to deal with SIGPIPE in mhl so it doesn't print
        "Broken pipe" if you quit out of the moreproc.

        * Documentation: Added a note to MACHINES about Irix make. Added a
        pointer to the online copy of the MH book in INSTALL. Added
        some additional information to the whatnow and packf man pages,
        suggested by Jerry Peek <jpeek@jpeek.com>.

        * Updated INSTALL, FAQ, etc to not refer to Richard as the
        maintainer or math.gatech.edu as the home any more.

1999-02-06  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-1.0.

        * Merged mbx_open and mbx_Xopen in dropsbr.c.  Fixed
          mbx_open so that the mode of zero length maildrops
          would not be changed.

        * Replaced the substitute version of snprintf() with the
          one from the Apache web server.

        * Changed to default mode for creating new messages to 0600
          (this should have been done a long time ago).

        * Changed "flist" to handle searching for multiple sequences
          for each folder.  Also flist will now correctly split
          Unseen-Sequence if it consists of multiple sequences.

        * Added new switches `-unlink' and `-nounlink' to "refile".

        * Added new switches `-unlink' and `-nounlink' to "rmm".

        * More cleanups of slocal output.  Changed adorn() to
          send to stdout, instead of stderr (to match rest of
          verbose printing).

        * Merged mbx_create() into mbx_open, so that creating and
          opening a nonexistent maildrop is done atomically.  This
          removes a bad race condition.

        * Fixed bug that caused slocal to be unable to save to MMDF
          style drop file.

        * Added new wrapper function usr_folder() to slocal.c to
          handle adding message to folder (currently, it still uses
          usr_pipe() to call rcvstore).

        * seq_list() checks for empty folder before scanning for
          sequence information.

        * num_digits() in flist.c and folder.c now returns correct
          value for 0.  Also added sanity check.

        * folder_delmsgs() now correctly decrements internal message
          count.

        * Don't attempt to read sequence information if folder
          is empty.

        * Split seq_read into seq_public and seq_private.

        * Small change to sigmsg.awk, since newer versions of gawk
          interpret 034 as octal.

        * In flist, don't scan for sequence information in empty folder.

        * Updated mhn.defaults.sh to output profile entries for mhshow,
          mhstore, and mhbuild.

        * Changed configuration parameter "mhn-access-ftp" to
          "nmh-access-ftp".  Updated man pages

        * Moved the code in InitMultipart to reverse the order of the
          parts in a multipart, into its own function "reverse_parts()".

        * Changed code in mhbuildsbr.c to store unencoded content
          in the c_cefile structure when building.

        * Changed code in mhoutsbr.c to look for unencoded content
          in the c_cefile structure when outputing message.

        * Changed configuration parameter "mhn-cache" and
          "mhn-private-cache", to "nmh-cache" and "nmh-private-cache",
          since it is used in mhstore, mhlist, and mhshow.  Updated man pages

        * Change configuration parameter "mhn-storage" to
          "nmh-storage", since it is now used in mhstore, mhlist,
          and mhshow.  Updated man pages

        * Add autoconf support for KPOP (kerberized pop).

        * Add autoconf support for Hesiod.

        * Split routines to output a message given a Content structure
          (output_message, output_content, write7Bit, etc..) to a new
          file "mhoutsbr.c".

        * Split output_content(), into output_content() and build_headers().

        * Changed copy_some_headers() in mhstoresbr.c, to use the linked
          list of header fields, rather than reopening the message.

        * Added free_header() to mhfree.c to free structures containing
          header field information.

        * Changed get_content() to use the linked list of header fields
          when parsing the various MIME headers (Content-XXX).

        * Changed get_content() to store linked list of header field
          values when parsing a content.

        * Changed mhbuild, mhn, mhlist, mhshow, mhstore, to use the
          routines in mhcachesbr.c to handle the content cache.

        * Split various funtions (find_cache, find_cache_aux, find_cache_aux2,
          cache_content) into new file mhcachesbr.c.

        * More calls to sprintf/strcpy (primarily in mhparse.c
          and mhbuildsbr.c) converted to snprintf/strncpy.

        * When a message is displayed with `mhshow', it is now
          removed from the "unseen" sequence.

        * Change the default "showmimeproc" to "mhshow".

        * Split "mhn -show" off into separate command "mhshow".

        * Split "mhn -store" off into separate command "mhstore".

        * Split "mhn -list" off into separate command "mhlist".

        * Add sanity checks to context_find(), context_replace(),
          and context_del(), to abort if context file hasn't been
          read.

        * Add calls to context_read(), to the beginning of all nmh
          commands (instead of being called indirectly by context_find).

        * Changes the "substitute" version of vsnprintf/snprintf for
          operating systems without native versions, to just call the
          native vsprintf(), and ignore the buffer length.   This is
          faster, but less secure than the previous version that used
          temporary files.  This should only be a problem for systems
          which do not have a native snprintf(), and require `inc' to
          be setuid/setgid.

        * Lots more calls to sprintf/strcpy converted to snprintf/strncpy.

        * Changes client() routine to take additional parameter, which is
          the buffer length of the parameter "response".  Then added
          buffer length checks for this parameter.

        * Changed getws() to get_fields(), since that is apparently the
          name of a wide character version of gets() on some archetitures.

        * Lots of sprintf/strcpy calls converted to snprintf/strncpy.

        * Change the code in most of the commands that take multiple
          message names/sequences/ranges on the command, such that
          the msgs array is expanded dynamically.  This removes most
          of the limits on the length of command lines.

        * Add additional parameter to copyip(), to specify the
          maximum number of strings that can be copied (security
          fix).

        * Create new function getarguments(), to massage the argument
          vector before parsing it (add any arguments from your
          profile to the beginning of the argument vector).  This
          also removed the general limit on the number of command line
          arguments.

1998-07-04  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.27.

        * Added a new command "delete", that is available during
          a "whatnow" session.  It is equivalent to "quit -delete".

        * Added another parameter to editfile (in whatnowsbr.c),
          that controls whether editfile should remember the last
          program that was exec'ed.  This way the whatnow command
          "mime", will not be re-executed if "edit" is later given
          with no arguments.

        * Changed whatnowsbr.c, so that whatnow doesn't abort if
          mhbuild returns an error.

        * Added parameter to sendsbr(), so you may specify whether to
          rename the draft file.

        * Pass delay time to splitmsg() as a parameter, rather than
          use a global variable.

        * Moved code to rename draft file after sending message from
          splitmsg and sendaux, to sendsbr.

        * Removed all the code in viamail to split messages and then
          mail them.  Replaced this with the standard sendsbr.c routines.

        * Changed sendsbr(), so that when splitting messages into
          messages of type "message/partial", the header fields that
          are copied are more compliant with RFC-2046.

        * Fixed mhbuild to track temporary files better.  They are
          now correctly removed when mhbuild aborts.

        * Created a new man page for "sendfiles".  The information
          about "mhn -viamail" in the "mhn" man page was moved to
          this new page.

        * Changed the name of the "viamail" shell script to
          "sendfiles".  Modified "sendfiles" to use the new
          viamail program.

        * Moved the functionality for "mhn -viamail" out of mhn,
          and into a separate executable called "viamail".

        * When storing MIME contents to a folder using mhn -store,
          they are now accumulated in a temporary file, and then added
          to the folder using folder_addmsg().

        * Moved code to save content to a folder from store_content
          to new function output_content_folder.

        * Moved code to save content to file from store_content to
          new function output_content_file.

        * Moved code to parse storage format string from store_content
          to new function parse_format_string.

        * Fix copy_some_headers() in mhstoresbr.c, so that the
          correct header fields in the first enclosing message/partial
          will be copied (according to RFC2046), when using mhn -store
          to reassemble messages of type message/partial.

        * Fixed bug to openFTP() in mhparse.c, that caused the
          tmp file to not be removed, when transferring a
          message/external file from ftp.

        * Moved the code in mhparse.c to process -auto switch (scan
          contents for the attribute "name"), to a new function
          "get_storeproc" in mhstoresbr.c.

        * Moved routines to free data structures related to MIME
          content from mhparse.c and mhbuildsbr.c, to new file
          mhfree.c.

        * Moved code to show/display MIME content into new
          file mhshowsbr.c.

        * Moved code to store MIME content from into
          new file mhstoresbr.c

        * Moved code to parse MIME content into new
          file mhparse.c.

        * Moved code to list information about MIME content
          into new file mhlistsbr.c.

        * Move part_ok(), type_ok(), content_error(), flush_errors(),
          and set_endian() to new file mhmisc.c.

        * Start to isolate the code to show, list, and store MIME
          messages.  One side effect is that only one flag (-show,
          -list, or -store) can be used at a time now.

        * mhn -store -auto wasn't storing file in correct directory.

        * Removed a few dead variables from sbr/ruserpass.c

        * move code for creating tmp files, and renaming the
          the composition draft in mhbuild, from build_mime()
          to main().

        * remove left-over code in mhbuild.c, mhbuildsbr.c, for
          the -[no]auto switch (which isn't used in mhbuild).

        * split mhn.c into mhn.c and mhnsbr.c (name later changed
          to mhparse.c).

        * split mhbuild.c into mhbuild.c and mhbuildsbr.c.

1998-05-25  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.26.

        * Added (unlisted) options [no]dashstuffing to send, post,
          and whatnow to determine whether to do RFC934 quoting
          (dashstuffing) for encapsulated BCC messages.  The default
          is still the same (dashstuffing).

        * Changed the undocumented feature "nodashmunging" in forw
          and mhl, into the documented feature "nodashstuffing".  The
          default for forw, is still "dashstuffing" for backward
          compatibility, although I don't believe that bursting
          RFC934 digests is very common anymore.

        * Added an option to define REALLYDUMB in the default config.h.
          But it is not on by default.

        * moved creation of config file mts.conf from zotnet/mts
          to etc.  This simplified the Makefile in zotnet/mts.

        * simplified directory support/general to etc.

        * removed unneeded directory support/bboards.

        * split getusername() into getusername() and getuserinfo().

        * Changed getusr() routine to getusername().

        * Slight cleanup in folder_pack.c on code that records the new
          number of the "cur" message when packing.

1998-05-08  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.25.

        * Change install process, so that hard linking the correct mts
          library to libmts.a, is not necessary.  The final link process
          uses the original name of the library.

        * Fixed bug in flist.c and folder.c, so that symbolic links which
          point to directories, will not decrement the number of directory
          links remaining.

        * Split the function list_content (in mhn.c and mhbuild.c) into
          list_content and list_debug.

        * Don't pack (folder -pack) an empty folder.

        * Exit gracefully in flist.c, if no sequence is specified,
          and no "Unseen-Sequence" is given in nmh profile.

1998-02-27  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.24.

        * Small clarification to the man page for `ali'.

        * Fix bug in inc.c so that if both flags `-file' and `-truncate'
          are given, that order doesn't matter.

        * Fix bug in seq_list.c when realloc'ing for
          large sequence line.

1998-02-23  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.23.

        * Add new section on "Transfer Encodings" to man page for mhbuild.

        * In mhbuild.c, split compose_content into compose_content
          (parse and execute composition string), and scan_content (scan
          content, decided transfer encoding, check for clash with boundary
          string).  I did a good amount of rearranging of this code.

        * Moved definitions for data structures for parsing MIME
          messages from mhn.c and mhbuild.c to a new include
          file h/mhnsbr.h.

        * Small amount of rearranging in sendsbr.c

        * Small changes to MAIL.FILTERING file.

        * Add the file MAIL.FILTERING to nmh distribution.

        * Add line to packf so that if message begins with
          "X-Envelope-From:" field, it is converted to "From ".

        * Fix packf to add "From " line to beginning of message,
          even if Return-Path doesn't exist.

        * Add note to MACHINES file that on Linux, configure
          doesn't find the functions sigsetjmp/siglongjmp.

        * Fix configuration for machines that don't have (or find)
          sigsetjmp/siglongjmp.

1998-02-11  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.22.

        * Add a configure check for sigsetjmp.  Add some conditional
          #define's in h/signals.h in case it's not found.

        * Added additional notes about -auto switch in mhn man page.

        * Added note about MM_CHARSET environment variable to
          mh-profile(5) man page.

        * Fix signal problem in mhn.c (change setjmp/longjmp to
          sigsetjmp/siglongjmp).

1998-02-09  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.22-pre1.

        * Changed the first line in mhl.format from
          " -- using template mhl.format -- " to a blank line.

        * Added note about automimeproc to mh-profile man page.

        * Reorganize the main entry point for parsing a MIME message
          or file in mhn.  Add new function parse_file() as new main
          entry point for parsing MIME files.

        * Add note to mhn man page, that "mhn -file -" will accept the
          source message on the standard input.

        * Changed a sanity check in folder_realloc that was too strict.

        * -norfc934mode is now the default for mhbuild,
          rather than -rfc934mode.

        * Fix mhbuild, so that Content-Description and RFC-822 comments
          from #forw directive will be correctly included if there is
          only one message.

        * Change mhn to correctly default parts of multipart/digest to
          message/rfc822 (leftover code from rfc934mode was removed).

        * Restore HP specific code to zotnet/tws/lexstring.c.  Apparently
          it is still needed.

1998-02-06  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.21.

        * If the file given to mhbuild is "-", then accept the draft on
          standard input, and output the MIME message to standard output.

        * Cleaned up code in mhbuild.c that decides what transfer
          encoding to use.

        * Cleaned up code in mhbuild.c that decides what character set
          to use for text contents.

        * Removed old hpux specific code from zotnet/tws/lexstring.c

1998-02-02  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.21-pre2.

        * Added the "decode" variable to mhl.format and mhl.header.

        * Added new variable "decode" to mhlsbr.c to decode text in
          header fields as per RFC-2047.

        * Make sure that when decoding RFC-2047 header fields, that any
          spaces at the ends of the encoded text are not ignored, but the
          spaces between encoded word are.

        * Removed #ifdef's for MIME.  MIME support is always compiled in.

        * scan/inc will now decode both Subject and From lines as
          RFC-2047 encoded header fields.

        * Added new function write_charset_8bit() to sbr.  It returns
          the character set to use for 8bit text in composition draft.
          Changed mhbuild to use this function.

        * Split mhn man page into man pages for mhn and mhbuild.

        * mhn -show will only now only use default method for content
          of type plain, if it is NOT a part of a multipart/alternative.

        * Split mhn -build into mhbuild.  Did some code cleanup.

        * Added support for %(decode) to fmtdump.c.

        * check_charset() now accepts US-ASCII as a subset of any
          ISO-8859-X character set.

        * Changed the default "showproc" to mhl, instead of the
          pager more.

        * When reading file into mhn composition file, only need read
          permissions, not write permissions.

        * Added own version of strcasecmp to distribution, since
          nmh calls it frequently with NULL pointers (ughh).

        * Replaced uleq.c with strcasecmp.  Removed uleq.c from
          distribution.

1998-01-22  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.21-pre1.

        * If a message is missing charset parameter to text/plain, show
          will assume US-ASCII, rather than just calling showmimeproc.

        * Change show.c and mshcmds.c to use check_charset to see if text
          message contains valid character set.

        * Added new scan format file "scan.nomime" to support/general
          that doesn't do any RFC-2047 decoding.

        * Modified all the scan format files in support/general to do
          RFC-2047 decoding of Subject field.

        * Did more work on sbr/fmt_rfc2047.c, so that it will correctly
          ignore whitespace between two valid encoded words, but not
          between an encoded word and normal text.

        * Created new file sbr/check_charset.c.  Moved code from
          fmt_rfc2047.c to check for valid character set to this file.

        * Added format escape %(decode) to decode contents of "str" register
          as a RFC-2047 header field.

        * The command install-mh now recognizes the switches -version
          and -help.

        * Added a new argument to print_help.c to decide whether to
          print profile entries (needed for install-mh to prevent weird
          loops).

        * Changed folder_read.c and folder_realloc.c so that mp->lowoff
          is initialize to max (mp->lowmsg, 1) rather than always 1.

        * Changed macros for sequence/attribute manipulation so that
          message status array doesn't need to always start at 1.

        * Small cleanups in folder_realloc().

1998-01-09  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.20.

        * Added configure option --with-pager=PAGER.

        * Added configure option --with-editor=EDITOR.

        * Changed the default format file for mhl (mhl.format) to
          also ignore (not display) the header fields Content-Type,
          Content-Transfer-Encoding, and Content-ID

        * Fixed core dump in addrsbr.c when using %(proper) format function
          and the To: line was missing.

        * Added the file ZSH.COMPLETION to the distribution.

1998-01-04  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.20-pre2.

        * Added new switch -snoop to both `msgchk' and `inc', so you can
          watch the POP transaction.

        * Changed "replgroupcomps" to check for Mail-Followup-To header
          first, and use it if available.

        * Changed "replcomps" to check for Mail-Reply-To header
          first, and use it if available.

1998-01-03  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.20-pre1.

        * Changed seq_list.c to dynamically enlarge the buffer for
          collecting the message ranges in a long sequence line.
          This should remove the last hard limit on the size of a
          sequence line.

        * Changed seq_read.c so that can read long sequence lines.
          It will use multiple calls to m_getfld() when m_getfld()
          returns the state FLDPLUS.

        * Changed brkstring.c to dynamically add more space for pointers
          if necessary.  This is needed when splitting up large sequence
          lines.

        * Did some small cleanups in seq_save.c.

        * Added new switches `-[no]unseen' to rcvstore, to control
          whether new messages are added to Unseen-Sequence.

        * Moved locking routines (zotnet/mts/lock.c) to sbr/lock_file.c

        * Changed the internal UNSEEN flag to SELECT_UNSEEN which is
          more appropriate.  Changed the MHPATH flag to ALLOW_NEW.

        * Changed "replcomps" to not include CC and TO lines so that
          that reply message is only directed at the author of the
          message to which you are replying.

        * Added new switch `-group' to command repl, which causes repl
          to use new forms file "replgroupcomps".  This is intended for
          making group replies.

        * Removed #ifdef for ATHENA.

1997-12-28  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.19.

        * Fix repl,forw so that switch `-form file' will not abort
          as ambiguious (silly mistake on my part).

        * Cleaned up the mhn man page.  Added info about a few escapes
          for the formatting/display strings that were not documented
          (%%, %t).  Moved the BNF grammar for the mime composition file,
          to the end of the man page.

        * Added the options -[no]format to the command repl.  The
          switch `-format' will filter the message to which you are
          replying with the standard message filter "mhl.reply", which
          is now included in the distribution.  The `-noformat' option
          will negate the use of -format or -filter and not include
          the message to which you are replying in the draft.

        * Did some cleaning and reorganization on many of the man
          pages.

        * Added debugging switch `-debug' to mhparam, which displays
          the values of all `procs' (and some other misc configuration
          info) that nmh keeps in global variables.

        * When using `refile -preserve', if a conflict occurs, then use
          the next available number above the message number you wish
          to preserve.

        * In forw.c, split the code for creating MIME style forwarding
          out of copy_draft, and into copy_mime_draft.

        * Move routines in mark.c to print sequences, into new
          file sbr/seq_print.c

        * flist will now update the current folder.

        * Added the switches -[no]fast to flist, to replace
          -[no]total.  The previous switches are still accepted
          but now undocumented.

        * More reorganization in flist of the code for
          traversing folders.

        * The command "flist +foo -all" will now scan the folder
          "foo" and all its 1st level children.

        * Add missing include file <h/mh.h> to sbr/snprintf.c

        * Fix alarm bug in rcvtty, so that when it calls external
          process, the alarm is never longer than 30 minutes.

1997-12-17  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.18.

        * Fixed bug in mark, so that "mark -list -seq foo" will
          correctly indicate if "foo" is a private sequence.  I found
          this bug mentioned in Jerry Peek's book.

        * Simplified the code in seq_setcur(), since seq_addmsg() now
          retains the public/private status of sequences.

        * Changed sequence handling so that if the switches -public
          or -nopublic, are not specified for the commands mark, pick,
          or rcvstore, then existing sequences will retain their
          previous public/private status.

        * mhparam now handles the mh-sequences profile entry
          correctly.

        * flist -all will now also check readonly folders (for
          private sequences).

        * Improve the leaf optimization for folder command.
          It will now track the number of directories in a folder,
          and stop stat'ing files once it has hit all the subfolders.

        * Renamed m_getfolder to getfolder.  Changed getfolder to
          take option to determine whether it should get current
          folder, or just default folder (Inbox).  Changed rcvstore,
          inc, and rmf to use the new getfolder.

        * flist now indicates if a sequence is private.

        * Change WUNTRACED to 0, in pidwait.c, so that commands will
          wait for stopped processes.

        * conflict will dynamically allocate space for group names,
          so it can now handle system with more than 100 groups.

1997-12-09  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.18-pre4.

        * Check if we have enough message status space, before we
          call folder_realloc() in burst, mhpath, and m_draft().

        * mhn will now correctly identify a formatting string of "-"
          for the option -store, and send content to stdout.

        * Change the way that memory for message status is
          allocated.  It is dynamcially allocated separately from
          the folder/message structure.  This required changing
          folder_read.c, folder_realloc.c, folder_free.c.

        * Removed all the MTR code (experimental code for message
          status allocation).

        * Renamed m_readfolder.c to folder_read.c and simplified
          the code.

        * Renamed m_freefolder.c to folder_free.c.

        * Add function trim() to slocal.c to pretty print
          the debugging output.

        * Changed the name of m_packfolder() to folder_pack().
          Changed the name of m_remsg() to folder_realloc().

Wed Dec  3 23:33:38 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.18-pre3.

        * Changed installation to add `flists' which is hard linked
          to `flist'.  This is a equivalent to `flist -all'.

        * For flist, -showzero is on by default.

        * Major changes to flist.  Default is now for flist to search
          current folder.  The switch `-all' is now used to specify
          searching all top level folders.  The new switch `-showzero'
          is used to print out folders that don't contain any messages
          in the given sequence.

        * Split BuildFolderList in flist.c into 2 functions
          (BuildFolderList, BuildFolderListR).  Changed these functions
          so that flist now does better leaf optimization, and will stop
          stat'ing directory entries when it knows it has hit all the
          subdirectories of a given directory.

        * Reorganized code in folder.c, so that all relevant folders
          are scanned first and information recorded.  Then all the
          folder summaries at printed out at one time.

        * Made the options of folder(s) more orthogonal.  Now
          "folder -all -noheader -nototal" will do the right thing.

        * Added `-noall' switch to folder, for completeness.

        * Changed the default mode for creation of new folders
          to 0700 (was 0711).

        * Slightly changed the format for flist.  It now indicates
          if a folder is current.  Also the width of the various
          fields are now calculated at runtime.

        * Changed the format for folder(s).  Folder names
          are now left justified.  The width of the various fields
          are calculated at runtime.

Sun Nov 30 19:14:53 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.18-pre2.

        * Add paragraph to man page for install-mh and to INSTALL file
          about checking for global mh.profile.

        * Renamed m_find() to context_find().
          Renamed m_replace() to context_replace().
          Renamed m_delete() to context_del().
          Renamed m_update() to context_save().
          Renamed m_getdefs() to context_read().
          Renamed m_foil() to context_foil().

        * Change rcvstore to use routine folder_addmsg(), instead of
          adding message to folder itself.

        * Changed refile, so that if the switch -preserve is used,
          and a conflict occurs for a particular folder, then folder_addmsg()
          will just use next highest available number for that folder,
          instead of exiting.

        * Make folder_addmsg() more robust.  It will make repeated
          attempts to link file into folder if link returns with
          the error EEXIST.

        * Fix bug, so that that if forking sendmail, HELO will be sent
          unless clientname: option is defined but empty (so now it
          is the same as the direct smtp code).

        * Changed sprintb to snprintb (now we pass the buffer length
          to new routine).  Changed code to use new function.

        * Added snprintf to sbr. Added configure check to build it
          if you don't have a native version (but haven't changed much
          code to use it yet).

Thu Nov 13 18:42:18 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.18-pre1.

        * Fixed alarm bug in slocal, so that alarm is never
          called with a value larger than 30 mintues.

        * Fixed race condition in rmm and refile, so that
          context is updated before external rmmproc is called.

        * Removed all the OVERHEAD code.

        * Move code to add message to folder from refile.c
          to folder_addmsg.c

Fri Jul 25 19:39:29 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Did some rearranging of the internals of inc.c.

        * Make -inplace the default for anno, forw, dist, and repl.

        * Changed --enable-smtp to --with-mts={smtp,sendmail}

        * Created new directory mts/sendmail for direct sendmail
          interface (although it currently still uses SMTP).

        * Removed all the TMA (trusted mail agent) code

        * Removed all the TTYD (terminal access daemon) code

        * Removed all the MF (uucp filtering) code.

        * Removed all the code for BERK.

        * Removed all the code for stand-alone delivery (MHMTS).

        * Split the file mts/sendmail/smail.c into sendmail.c and
          smtp.c.  Changed the name of the directory to mts/smtp.

        * Changed autoconf to use @sysconfdir@ for location of
          configuration files.

        * Changed #define in mhn.c from FTP to BUILTIN_FTP.

Mon Jul 21 03:22:34 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.17.

        * MAKEDEFS weren't passed down to recursive makes correctly.

        * slocal.c now checks for UTMP_FILE and _PATH_UTMP instead
          of hard-coding "/etc/utmp".

        * rcvtty.c check for _PATH_UTMP if UTMP_FILE is not
          defined.

        * Remove configure checks for ulong and ushort.  Changed
          code to just use unsigned {short, long}.

        * Change addmsg function in refile.c to return new
          number of refiled message.

        * Added check in get_returnpath for empty unixbuf.

        * Cleanup of sbr/pidstatus to use more POSIX macros
          for return value of wait().

        * Change configure to also check /bin for "more".

Sat Jul 12 00:02:23 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.16.

Mon Jun 23 20:13:24 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Added automimeproc, which should replace automhnproc.

        * multipart messages will no longer abort for messages
          of type 8bit or binary (although we still can't really
          deal with binary messages, yet).

        * Fix double free of c_storage.  From John MacMillan.

        * mhn now treats unknown subtypes of "text" as text/plain.

        * mhn changed so that specifying mhn-show-multipart, or
          mhn-show-multipart/{mixed, alternate, etc...) will override
          the use of the internal method for displaying these types.
          Previously mhn would always use the internal method for subtypes
          mixed, alternate, digest, and parallel (even if an alternate
          method was specified in mhn.defaults).

        * mhn show treats unknown subtypes of multipart, as type
          multipart/mixed (as specified RFC2046).

        * mhn checks for the parameter "name" rather than "x-name".
          From MH-6.8.4 patch.

        * Fix double free of ctinfo in user_content when using
          #forw with single message.  From John MacMillan (and
          MH-6.8.4 patch).

        * Changed -mhnproc switch for show, to -showmimeproc.

        * Changed profile entry "mhnproc" to "showmimeproc".

        * Added "mime" option to "whatnow", which calls the program
          "buildmimeproc" (default is mhn -build) to process MIME
           composition files.

        * Added -build switch to mhn, to process MIME composition
          files.

        * Did some reorganizing of mhn.c.

        * Changed casting in mts/sendmail/smail.c from (char) to
          (signed char) so SMTP reply codes work correctly for machines
          which used unsigned chars by default.

Sat Jun 21 01:21:47 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.15.

        * Added new form "scan.unseen" to distribution.  It marks messages
          which are in any sequence in Unseen-Sequence.

        * Do some rearranging of date/time code in zotnet/tws/dtime.c

        * Fix sign extension bugs in fmt_scan.c.

        * Fix m_atoi.c so that strings ending in non-digit characters
          return 0.

        * Split code in burst.c so that finding delimiters of digested
          messages and bursting a message into multiple messages are
          two separate functions (find_delim and burst).

        * Add workaround fo AC_PATH_PROG in configure.in, so
          that BSD4.4 machines can find sendmail, vi, more.

        * Added "-width" option to rcvtty.

        * Change a few variable names in zotnet/mts/client.c since
          they conflict with defines on AIX.

        * Makefile in zotnet/tws assumes lexing of dtimep.lex was
          unsuccessful if resulting file is less than 500 lines long
          (rather than 10, which was previous value), since AIX
          sed gives mangled file of about 200 lines.

        * Extract code in rcvstore.c to link message into folder,
          and put in own subroutine.

        * Extract code in refile.c to link message into folder,
          and put in own subroutine.

        * Moved code to remove messages from folder into own
          routine "folder_delmsgs" in sbr.  Changed rmm.c and
          refile.c to use new routine.

Fri May 16 06:09:31 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Renamed m_seqok to seq_nameok.

        * Changed m_setunseen, msh, mshcmds, flist, and scan to use
          seq_getnum.

        * Changed m_seqflag to return the number of a sequence rather
          than its bit flag.  Changed its name to seq_getnum and renamed
          file to sbr/seq_getnum.c.

        * Removed function m_seqnew and file sbr/m_seqnew.c since it is
          no longer used.

        * Added zero switch to m_seqadd function to zero out bits before
          adding message to sequence.

        * Renamed function m_setvis to m_setunseen, and renamed
          corresponding file in sbr.

        * Renamed function m_setseq to m_setprev, and renamed corresponding
          file in sbr.

        * Changed mark.c and pick.c to use m_seqaddsel and m_seqdelsel.

        * Added new function m_seqdelsel to m_seqdel.c, which deletes
          all selected messages from a sequence.

        * Added new function m_seqaddsel to m_seqadd.c, which adds all
          selected messages to a sequence.

        * Split sbr/m_seqnew.c into m_seqadd.c, m_seqdel.c, m_seqnew.c,
          and m_seqok.c.

Thu May 15 00:53:17 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Renamed function pack_folder to m_packfolder, and moved it
          from uip/folder.c into its own file sbr/m_packfolder.c

Wed May 14 23:38:00 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Changed function m_gmsg to m_readfolder.  Renamed file
          sbr/m_gmsg.c to sbr/m_readfolder.c.

Mon May  5 19:57:11 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Expanded rcvtty man page, and added small patch from
          MH-6.8.4 distribution.

Fri May  2 15:24:34 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.14.

        * Comment out configure test and code for tgetent to allocate its
          own termcap buffer when passed a NULL argument.

Sat Apr 26 03:46:38 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Added new options `-checkmime', `-nocheckmime', and `-mhnproc'
          to show.  Restructured code to handle options to various
          `procs' better.  Deprecated `-noshowproc' option and NOMHNPROC
          environment variable.

        * Added new man page `mh-draft' which documents the
          draft folder facility in nmh.

        * Renamed fmtsbr.h to fmt_scan.h.  Renamed fmtcompile.h
          to fmt_compile.h.

        * split fmtsbr.c into fmt_scan.c and fmt_new.c.  Renamed
          fmtcompile.c to fmt_compile.c, and formataddr.c to
          fmt_addr.c.

        * `send -help' wasn't showing the -(no)mime and -split
          options.

Fri Apr 25 02:50:36 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.13.

        * Changed mhpath so it doesn't abort if a message sequence
          such as "mhpath all" expands to more than 1000 messages.
          Also mhpath now dynamically reallocated space for message
          names (The number of command line arguments is still limited
          to MAXARGS).

        * Did some general restructuring of the code in folder.c
          that checks for folder information, and prints it.

Thu Apr 24 01:04:37 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Changed `folder' to reallocate space for folder names if
          necessary.  So `folders' can now handle more than 300 folders.

Tue Apr 22 14:01:26 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Change configure to use a compile check to see if the tm struct
          has tm_gmtoff, rather than using egrep.

Mon Apr 21 02:19:17 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.12.

        * Had set_exists and unset_exists macros backwards.

        * Released nmh-0.11.

Thu Apr 10 02:39:53 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Added documentation to mh-profile.man about the various
          `procs' (mhlproc, showproc, lproc, etc...).

        * Replace the bit twiddling for SELECTED, UNSEEN, and
          mp->attrstats with macros.

        * If system doesn't have SIGEMT (like Linux), then use SIGTERM
          in msh.c instead.

        * Change fstat to stat in m_gmsg.c since Linux wants
          to hide dd->dd_fd.

        * Merge Linux patch sent in by Michel Oosterhof (original
          patch from bsa@kf8nh.wariat.org).

        * Document an undocumented MH feature.  mhn -form mhl.null
          will suppress the display of the message header.

        * mhparam will now return "mhparam etcdir".

        * Add catproc to /config/config.c and use that in show.c
          and mshcmds.c, rather than hard coding in /bin/cat.

        * Add mhnproc to the list of `procs' in mh-profile.man.

        * Add configure test for lorder and tsort commands.

        * Commented out the padding in the `msgs` struct in h/mh.h

        * Change m_gmsg.c to allocate elements to the `info' array by
          500 elements at a time (rather than MAXFOLDERS / 5).

        * Add note to man page for mhmail that zero length messages are
          not sent.  Need to use -body "" to send empty messages.

        * zotnet/mts/mts.c : compare character with '\0', not NULL.

        * sbr/getcpy.c : assign '\0' to character, not NULL.

        * add m_fmsg to most programs in uip so that they explicitly free
          folder/message structure when done with folder.

        * uip/slocal.c : cleanup processing of sender.  Make sure it is
          defined even if message is missing "From " line.

Mon Mar 31 03:37:35 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.10.

Sun Mar 30 21:46:17 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Add configure check for <locale.h>.  Turn on LOCALE support
          by default.

Thu Mar 20 03:21:24 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Reversed previous decision to retain "From " lines in slocal.
          The "From " line is now removed from all messages.

        * inc now saves the date from the "From " envelope in the
          Delivery-Date header for all messages.

        * sbr/m_getfld.c: Clean up processing of Return-Path and
          Delivery-Date from the "From " envelope.

Mon Mar 17 19:03:36 1997  Richard Coleman  <coleman@math.gatech.edu>

        * client.c: cast iaddr to int before comparing return value
          of inet_addr with NOTOK.

Tue Mar 11 04:38:10 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Grep test for signal names was failing on some OS'es because
          of missing tabs in regex.

Sat Mar  8 01:58:22 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.09.

        * Move config files and format files to *.old before installing.

        * Add configure check for killpg.

        * msh.c: include <termios.h> instead of <termio.h> and
          <sys/ioctl.h>.

        * prompter.c: don't include <sys/ioctl.h> anymore.

Thu Mar  6 04:03:24 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Added `-mime' and `-nomime' options to `repl'.
          From MH-6.8.4 diff.

Tue Mar  4 03:10:37 1997  Richard Coleman  <coleman@math.gatech.edu>

        * ruserpass.c : removed conflicting prototypes.

        * rcvtty.c : Fixed rcvtty to obey terminal permissions granted
          by `mesg' command.  Previously only worked on BSD machines.

Mon Mar  3 00:18:59 1997  Richard Coleman  <coleman@math.gatech.edu>

        * rcvtty.c : Changed to use #define UTMP_FILE (if exists) rather
          than hard coded "/etc/utmp".

        * Released nmh-0.08.

        * Changed slocal to lock .maildelivery (or file given by -maildelivery)
          when accessing ndbm/db file for duplicate suppression, instead of
          locking database itself.

Thu Feb 27 05:28:09 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Added slocal action `mmdf' to deliver to a file in mmdf format.

        * Changed the slocal actions `file' and `>' to always deliver in
          mbox (uucp) format rather than be determined by RPATHS config
          option.

        * Changed the slocal action `mbox' to deliver in mbox (uucp) format
          rather than mmdf format.

        * slocal now adds Delivery-Date field to all messages (previously it
          only added it to messages when delivering them to a file). The
          "From " line is now retained on all messages if compiling with
          RPATHS, rather than being discarded.

        * rcvpack no longer adds the Delivery-Date field to messages.

Sun Feb 23 22:03:54 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Removed the script packmbox, since it's functionality has been
          added to packf.

        * Changed packf so that it uses mbox (uucp) format by default
          rather than mmdf format.  Added options -mbox and -mmdf to
          packf so you can choose the preferred format.

        * Changed rcvpack so that it uses mbox (uucp) format by default
          rather than mmdf format.  Added options -mbox and -mmdf to
          rcvpack so you can choose the preferred format.

Tue Feb 18 00:01:05 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Changed nmh to use dot locking by default (although you
          can still easily change this in config.h).

        * Simplified locking code.  Removed code allowing setting of
          locking type in mts.conf.  Now the locking type and locking
          directory (if any) can only be set at compile time.

Fri Feb 14 02:49:18 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Prefer getting timezone information from tm->gmtoff rather
          than tzset and external timezone variable.

Thu Feb 13 00:35:45 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Fixed typo in ruserpass.c in the variable toktabs.

        * When ruserpass was added to LIBOBJS, it was missing
          the suffix.

        * Released nmh-0.07.

Tue Feb 11 01:29:47 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Add check to configure, so that if ruserpass, or _ruserpass
          is not found, build version of ruserpass in sbr.

        * Added define's to discard.c, m_getfld.c, and scansbr.c so
          the code that manipulates internals of stdio, will build
          on SCO 5.x.

        * Added #define to control whether to compile the simple
          built-in FTP client in mhn.

        * Added configure check for ushort and ulong.  Change code
          to use ushort/ulong rather than u_short/u_long.

        * A couple of small cleanups in locking code.

        * Added configure check for gmtoff element in struct tm.

        * Added configure check for tzset.

Fri Feb  7 03:01:57 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.06.

        * Removed code for machines that don't have socket
          interface (how could they get mail anyway?).

        * Removed code for BSD41 machines.  I don't think there are
          many such machines around anymore.

        * Add configure check for function uname, and prefer it
          over gethostname.  General cleanup of zotnet/mts/mts.c.

        * Change all `lseek' calls to use POSIX symbolic constants
          SEEK_SET, SEEK_CUR, SEEK_END.

Thu Feb  6 01:16:30 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Check lex generated file in zotnet/tws and use
          pre-generated version if necessary.

        * Released nmh-0.05.

        * Change to use reliable signals on all platforms that have
          sigaction.  Change so that interrupted system calls are
          restarted for all signals except SIGALRM.  This fixes alarm
          handling code in smail.c for BSD based systems.

        * Added lorder and tsort commands so that created libs can
          be linked in one pass.

Tue Feb  4 01:33:00 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Changed pidwait so that while it is waiting for a child,
          it should block signals rather than ignore them.

Mon Feb  3 21:05:30 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Add checks to configure for dbm_open and -lndbm.

Thu Jan 30 05:15:42 1997  Richard Coleman  <coleman@math.gatech.edu>

        * folder -pop and folder -push were freeing some memory too
          quickly, which caused the entry popped from the stack to not
          become the current folder.

Wed Jan 29 01:28:02 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.04.

        * Define ospeed and PC in termsbr.c is OS doesn't have
          it.

Sun Jan 26 20:25:10 1997  Richard Coleman  <coleman@math.gatech.edu>

        * editfile will create a symbolic link to the altmsg if it
          can't make a link, on any machine supporting lstat.  Formerly
          this would happen only on BSD42 based machines.

Sat Jan 25 22:54:26 1997  Richard Coleman  <coleman@math.gatech.edu>

        * traverse (in popsbr.c) wasn't calling va_start before using
          variable argument list.  Fixes core dump in inc when using POP.

Fri Jan 24 03:27:59 1997  Richard Coleman  <coleman@math.gatech.edu>

        * The variable pass in remotemail needed to be set to
          NULL.  (From MH-6.8.4 diff).  Fixes core dump of msgchk when
          using POP.

        * inc and msgchk were using -rpop by default when configured
          with POP support.  Default is now -norpop.

Thu Jan 23 02:01:17 1997  Richard Coleman  <coleman@math.gatech.edu>

        * By default, post will now give the SMTP HELO command with
          the local hostname.  If you specify a hostname with the
          clientname: option in mts.conf file, post will give the
          HELO command with that name instead.  If the argument to the
          clientname: option is empty, no HELO command is given.
          (From the MH-6.8.4 diff)

Wed Jan 22 01:55:45 1997  Richard Coleman  <coleman@math.gatech.edu>

        * When using `-help' for a command, it will also print its
          profile compents from .mh_profile. (From MH-6.8.4 diff)

        * "slocal -file" will now correctly takes its input from
          a file (currently need to specify full path).

Sun Jan 19 20:37:21 1997  Richard Coleman  <coleman@math.gatech.edu>

        * "slocal -debug" will now issue a warning if a non-blank
          line in the .maildelivery file has less than 5 fields.

Sat Jan 18 02:26:41 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Changed slocal so that code for duplicate suppression
          (MH config was MSGID) is always built. Added the options
          -[no]suppressdup to slocal to turn this on/off.

Thu Jan 16 00:26:34 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.03.

        * Fixed problem where mark would core dump if no
          .mh_sequence file existed.

        * Fixed problem where slocal would core dump if -debug
          option was given, and certain headers were missing.

        * Added patch to slocal to add `folder' (+) action, which
          is shorthand for piping message to rcvstore.  Updated
          man page.

Wed Jan 15 21:30:17 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Changed flist option -unseen to -[no]all.  Cleaned up
          flist man page.

Fri Jan 10 20:36:33 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Fixed flist.  Changed the profile component `Folder-Order'
          to `Flist-Order.  Added option `-sequence' to flist, so
          you can specify the name of the sequence to search for.

Thu Jan  9 00:20:48 1997  Richard Coleman  <coleman@math.gatech.edu>

        * A few minor portability cleanups.  Changed to use PATH_MAX
          rather than MAXPATHLEN.  Don't assume ospeed variable exists
          in termsbr.c.  Removed some conflicting prototypes.

Wed Jan  8 11:05:02 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Add configure test to check if tgetent will accept NULL
          and allocate its own buffer.  Borrowed from zsh.

        * Changed libpath to etcpath.

Mon Jan  6 04:15:35 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Cleaned up source code and Makefiles, so that if your `make'
          supports the VPATH option, you can build nmh in a different
          directory from where the source code is located.

Fri Jan  3 05:05:18 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.02.

Wed Jan  1 17:41:52 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Split mhook man page into man pages for rcvdist, rcvpack,
          and rcvtty.

Tue Dec 31 03:07:48 1996  Richard Coleman  <coleman@math.gatech.edu>

        * Changed code to use strerror, rather than using sys_errlist
          and sys_nerr directly.

Mon Dec 30 02:15:25 1996  Richard Coleman  <coleman@math.gatech.edu>

        * -compat switch from install-mh removed.

        * Changed the default POP port from "pop" to "pop3".

Sat Dec 28 13:25:05 1996  Richard Coleman  <coleman@math.gatech.edu>

        * Changed mhn_defaults to mhn.defaults.  Changed create_mhn_defaults
          (again) to mhn.defaults.sh.  Changed find_program (again) to
          mhn.find.sh.  mhn.defaults.sh now takes the search path
          as an argument.  Default search path is now specified in Makefile
          rather than in script.

Fri Dec 27 16:34:01 1996  Richard Coleman  <coleman@math.gatech.edu>

        * Changed mtstailor file to mts.conf.  Updated man pages.

        * Changed si_value to si_val in mhn.c, since it conflicts with
          macro defined on Solaris.

Thu Dec 26 02:50:15 1996  Richard Coleman  <coleman@math.gatech.edu>

        * Added --enable-nmh-mhe (and --disable-nmh-mhe) to enable/disable
          support for Emacs front-end mhe.  It is on by default.

        * Added the following configure options: --enable-nmh-pop to
          enable client side pop support, --enable-nmh-smtp to enable
          SMTP support.  Client-side pop support now compiles.  Man
          pages for inc, msgchk, mh-chart now correctly added pop
          options if enabled.

Tue Dec 24 14:33:20 1996  Richard Coleman  <coleman@math.gatech.edu>

        * Added configure test for bug in C libraries where linker
          can't find ruserpass, but can find _ruserpass.

        * Fixed configure test so that termcap variable ospeed is
          correctly found.

Mon Dec 23 19:40:17 1996  Richard Coleman  <coleman@math.gatech.edu>

        * Source files converted to ANSI C.
        
        * md5 now compiled separately rather than being included
          in mhn.c.  Changed md5 to use memset and memcpy.

Fri Dec 20 02:29:37 1996  Richard Coleman  <coleman@math.gatech.edu>

        * Collected the error routines adios, advise, admonish, and advertise
          into one file (error.c), and did some rearranging of the code.

Thu Dec 19 19:05:29 1996  Richard Coleman  <coleman@math.gatech.edu>

        * Added awk script sigmsg.awk (originally written by
          Geoff Wing <mason@werple.apana.org.au> for zsh) to
          automatically generate signal messages for pidstatus.c.
          Added files sbr/signals.c, h/signals.h.  Code now uses
          sigprocmask to block signals (if available).  Code now uses
          signal blocking on non-BSD machines.

Wed Dec 18 01:55:17 1996  Richard Coleman  <coleman@math.gatech.edu>

        * Add configure check for ATTVIBUG.  From Soren's mh autoconf work.

        * Released nmh-0.01.

        * Added configure code to check for type of signals functions
          you have (POSIX or BSD style signals).  Added function
          SIGPROCMASK to simulate sigprocmask on machines that don't
          have POSIX signals.

Fri Dec 13 19:40:48 1996  Richard Coleman  <coleman@math.gatech.edu>

        * Added -version switch to all commands.  Also added to
          their man pages.

Mon Dec  9 16:36:54 1996  Richard Coleman  <coleman@math.gatech.edu>

        * Renamed uip/trmsbr.c to termsbr.c and changed it to use
          POSIX termios.h style functions if present.

Tue Dec  3 16:18:39 1996  Richard Coleman  <coleman@math.gatech.edu>

        * Changed support/general/bootmhn.sh to output new mhn_defaults
          file to standard output by default (makes it easier for testing).
          Changed name of script to create_mhn_defaults.  Changed bootmhn.findit
          script to find_program.

Sun Dec  1 10:00:00 1996  Richard Coleman  <coleman@math.gatech.edu>

        * Added patch to uip/folder.c from exmh distribution to
          speed up -recurse option.

        * Added flist command from exmh distribution.  It doesn't work
          yet, but it compiles :-)

        * Changed default location for install to
          /usr/local/nmh/{bin,etc,lib,man}.  Split files so that format
          and configuration files go in nmh/etc, and support binaries go
          in nmh/lib.  Of course, all this can now be changed in the top
          level Makefile. 

        * Started with mh-6.8.3 as based and converted to autoconf.
          Rewrote all the Makefiles.  Currently only works with sendmail/smtp.
          Pop support and plenty of other things, are now broken.
