NAME
       extcompose - compose reference to external data for inclusion in a
       mail message

SYNOPSIS
       extcompose filename

DESCRIPTION
       extcompose is intended primarily to be called from mailcap files by
       programs like mailto.

       extcompose allows a user on a properly-equipped workstation to enter
       the appropriate data that will enable a mail message to be sent with
       a reference to ``external'' data, that is, data that is not included
       in the mail message itself but is otherwise available on the network
       via a suitable mechanism.

       The filename specifies the external file.  The user is prompted for
       all other necessary information.  External data may be referenced as
       local files, as files available for FTP (anonymous or authenticated),
       or as data available via a mail server mechanism.  The user is asked
       to provide a MIME content-type value to describe the type of data
       being referenced, and to specify whether or not the data has been
       encoded with one of the algorithms for encoding data for email.
       (Such encoding is not recommended when used with externally
       referenced data.)
