-.SH HISTORY
-The
-.I \&.mh\(ruprofile
-contains only static information, which
-.B nmh
-programs will
-.B NOT
-update.  Changes in context are made to the
-.I context
-file kept in the users
-.B nmh
-directory.
-This includes, but is not limited to: the \*(lqCurrent\-Folder\*(rq entry
-and all private sequence information.  Public sequence information is
-kept in each folder in the file determined by the \*(lqmh\-sequences\*(rq
-profile entry (default is
-.IR \&.mh\(rusequences ).
-.PP
-The
-.I \&.mh\(ruprofile
-may override the path of the
-.I context
-file, by specifying a \*(lqcontext\*(rq entry (this must be in
-lower-case).  If the entry is not absolute (does not start with a
-\*(lq/\*(rq), then it is interpreted relative to the user's
-.B nmh
-directory.  As a result, you can actually have more than one set of
-private sequences by using different context files.
 .SH BUGS
 There is some question as to what kind of arguments should be placed
 in the profile as options.  In order to provide a clear answer, recall
-command line semantics of all
+the command line semantics of all
 .B nmh
 programs: conflicting switches
 (e.g.
 .B \-header
 and
 .BR \-noheader )
-may occur more than one time on the
-command line, with the last switch taking effect.  Other arguments, such
-as message sequences, filenames and folders, are always remembered on
-the invocation line and are not superseded by following arguments of
-the same type.  Hence, it is safe to place only switches (and their
-arguments) in the profile.
