-**  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 numbers          This option removes attachments by
-**                                attachment number from the draft.
