+ * This code is Copyright (c) 2002, by the authors of nmh. See the

+ * 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 [-v] files This option attaches the named files to
+ * the draft. -v displays the mhbuild
+ * directive that send(1) will use.
+ *
+ * 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.
