CTRL\-A's and a newline.
You may specify the name of the file in which to use with the
-`\-file\ name' switch. If you do specify the name of the file, it
+`\-file\ name' switch. If you do not specify the name of the file, it
will default to `msgbox'.
If the given file name points to an existing file, then the specified
messages will be appended to the end of the file, otherwise the file
will be created and the messages appended.
+\fIpackf\fR makes an mbox-style delimiter by examining the first line
+of the message. If the first line is a \*(lqReturn-Path:\*(rq
+field, its address and the current date and time are used. Otherwise,
+if the first line has an \*(lqX-Envelope-From:\*(rq field, its
+contents (which should already be in the correct format) are used.
+Otherwise, a dummy address and the current date and time are used.

Messages that are packed by \fIpackf\fR can be unpacked using
\fIinc\fR.
If the initial edit fails, \fIwhatnow\fR deletes your draft (by renaming
it with a leading comma); failure of a later edit preserves the draft.
+If the \fIbuildmimeproc\fR fails (returns a nonzero status), \fIwhatnow\fR
+simply prints a \*(lqWhat now?\*(rq prompt. \fIwhatnow\fR depends on the
+\fIbuildmimeproc\fR to tell the user that something went wrong.

If \fIwhatnowproc\fR is \fIwhatnow\fR, then \fIcomp\fR, \fIdist\fP,
\fIforw\fP, and \fIrepl\fP use a built\-in \fIwhatnow\fR, and do not
actually run the \fIwhatnow\fR program. Hence, if you define your own
