*
* This code is Copyright (c) 2002, by the authors of nmh. See the
* COPYRIGHT file in the root directory of the nmh distribution for
* complete copyright information.
*
* Several options have been added to ease the inclusion of attachments
* using the header field name mechanism added to anno and send. The
* -attach option is used to specify the header field name for attachments.
*
* Several commands have been added at the whatnow prompt:
*
* cd [ directory ] This option works just like the shell's
* cd command and lets the user change the
* directory from which attachments are
* taken so that long path names are not
* needed with every file.
*
* ls [ ls-options ] This option works just like the normal
* ls command and exists to allow the user
* to verify file names in the directory.
*
* pwd This option works just like the normal
* pwd command and exists to allow the user
* to verify the directory.
*
* attach files This option attaches the named files to
* the draft.
*
* alist [-ln] This option lists the attachments on the
* draft. -l gets long listings, -n gets
* numbered listings.
*
* detach files This option removes attachments from the
* detach -n numbers draft. This can be done by file name or
* by attachment number.
