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 ] [

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
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.
