NAME
     mpack - pack a file in MIME format

SYNOPSIS
     mpack [ -s subject ] [ -d descriptionfile ] [ -m maxsize ] [
     -c content-type ] file address ...
     mpack [ -s subject ] [ -d descriptionfile ] [ -m maxsize ] [
     -c content-type ] -o outputfile file
     mpack [ -s subject ] [ -d descriptionfile ] [ -m maxsize ] [
     -c content-type ] -n newsgroups file

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
     -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 gen-
          erated 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 vari-
          able, 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, output-
          file.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 /tmp.

     SPLITSIZE
          Default value of the -m switch.
