3 * whatnowsbr.c -- the WhatNow shell
7 * This code is Copyright (c) 2002, by the authors of nmh. See the
8 * COPYRIGHT file in the root directory of the nmh distribution for
9 * complete copyright information.
11 * Several options have been added to ease the inclusion of attachments
12 * using the header field name mechanism added to anno and send. The
13 * -attach option is used to specify the header field name for attachments.
15 * Several commands have been added at the whatnow prompt:
17 * cd [ directory ] This option works just like the shell's
18 * cd command and lets the user change the
19 * directory from which attachments are
20 * taken so that long path names are not
21 * needed with every file.
23 * ls [ ls-options ] This option works just like the normal
24 * ls command and exists to allow the user
25 * to verify file names in the directory.
27 * pwd This option works just like the normal
28 * pwd command and exists to allow the user
29 * to verify the directory.
31 * attach files This option attaches the named files to
34 * alist [-ln] This option lists the attachments on the
35 * draft. -l gets long listings, -n gets
38 * detach files This option removes attachments from the
39 * detach -n numbers draft. This can be done by file name or
40 * by attachment number.
