.SS "File Locking"
A few words on locking:
.B nmh
-has several methods for creating locks
-on files. When configuring
-.BR nmh ,
-you will need to decide on the
-locking style and locking directory (if any). The first controls the
-method of locking, the second says where lock files should be created.
+has two main uses for locking: locking the mail spool during mail
+incorporation, and locking metadata files (sequence files, the context)
+during updates. These locking methods can be configured separately
+from each other.
.PP
-To configure
-.B nmh
-for kernel locking, use the \*(lq--with-locking=flock\*(rq configure option if
-you want to use the
-.B flock
-system call; use \*(lq--with-locking=lockf\*(rq if
-you want to use the
-.B lockf
-system call; or use \*(lq--with-locking=fcntl\*(rq
-if you want to use the
-.B fcntl
-system call for kernel-level locking.
+For locking the mail spool, the
+.I spoollocking
+entry in
+.IR mh\-tailor (5)
+will control the locking algorithm to use when
+.B inc
+incorporates mail from the spool file. If no entry is given, a default
+based on the operating system type will be chosen.
.PP
-Instead of kernel locking, you can configure
-.B nmh
-to use dot locking by using \*(lq--with-locking=dot\*(rq. Dot locking
-specifies that
-a file should be created whose existence means \*(lqlocked\*(rq and
-whose non-existence means \*(lqunlocked\*(rq. The name of this file is
-constructed by appending \*(lq.lock\*(rq to the name of the file being
-locked. If \*(lq--enable-lockdir=directory\*(rq
+For locking all other files, the
+.I datalocking
+entry in
+.IR mh-profile (5)
+controls the locking algorithm used for all other file access.
+If no entry is given, the
+.I fcntl
+lock method will be chosen.
+.PP
+If you do not wish to use kernel\-based locking,
+.I dot
+locking is an option available.
+If \*(lq--enable-lockdir=directory\*(rq
is not specified at build time, lock files will be created
in the directory where the file being locked resides. Otherwise, lock
files will be created in the directory specified by
projects / nmh / blobdiff
