-** The inclusion of attachments is eased by
-** using the header field name mechanism added to anno and send.
-** The header field name for attachments is predefined.
-**
-** 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 This option lists the attachments on the
-** draft.
-**
-** detach files This option removes attachments from the
-** detach -n numbers draft. This can be done by file name or
-** by attachment number.
