DESCRIPTION

       The mpack program encodes the the named file in one or more MIME messages.  The  resulting
       messages are mailed to one or more recipients, written to a named file or set of files, or
       posted to a set of newsgroups.

OPTIONS

       -a     Set the Content-Disposition  to  attachment.   If  -a  is  not  used  the  Content-
              Disposition is inline.

       -s subject
              Set  the  Subject  header  field to Subject.  By default, mpack will prompt for the
              contents of the subject header.

       -d descriptionfile
              Include the contents of the file descriptionfile in an introductory section at  the
              beginning of the first generated message.

       -m maxsize
              Split  the message (if necessary) into partial messages, each not exceeding maxsize
              characters.  The default limit is the value of the SPLITSIZE environment  variable,
              or  no limit if the environment variable does not exist.  Specifying a maxsize of 0
              means there is no limit to the size of the generated message.

       -c content-type
              Label the included file as being of MIME type content-type, which must be a subtype
              of  application,  audio,  image,  or  video.   If  this  switch is not given, mpack
              examines the file to determine its type.

       -o outputfile
              Write the generated message to the file outputfile.   If  the  message  has  to  be
              split,  the  partial  messages  will instead be written to the files outputfile.01,
              outputfile.02, etc.

       -n newsgroups
              Post the generated message(s) to the comma-separated netnews newsgroups.

       file   Encode the named file.

       address ...
              Mail the generated messages to the specified addresses.

ENVIRONMENT

       TMPDIR Directory to store temporary files.  Default is /var/tmp.

       SPLITSIZE
              Default value of the -m switch.

                                                                                         MPACK(1)
