mpack/munpack version 1.5 for os2
Mpack and munpack are utilities for encoding and decoding
(respectively) binary files in MIME (Multipurpose Internet Mail
Extensions) format mail messages. For compatibility with older forms
of transferring binary files, the munpack program can also decode
messages in split-uuencoded format. The Macintosh version can also
decode messages in split-BinHex format.
Versions are included for unix, pc, os2, mac, amiga and archimedes
systems. The canonical FTP site for this software is
ftp.andrew.cmu.edu:pub/mpack/
This MIME implementation is intended to be as simple and portable as
possible. For a slightly more sophisticated MIME implementation, see
the program MetaMail, available via anonymous FTP to
thumper.bellcore.com, in directory pub/nsb
Decoding MIME messages:
To decode a MIME message, first save it to a text file. If possible,
save it with all headers included. Munpack can decode some MIME files
when the headers are missing or incomplete, other files it cannot
decode without having the information in the headers. In general,
messages which have a statement at the beginning that they are in MIME
format can be decoded without the headers. Messages which have been
split into multiple parts generally require all headers in order to be
reassembled and decoded.
Some LAN-based mail systems and some mail providers (including America
Online, as of the writing of this document) place the mail headers at
the bottom of the message, instead of at the top of the message. If
you are having problems decoding a MIME message on such a system, you
need to convert the mail back into the standard format by removing the
system's nonstandard headers and moving the standard Internet headers
to the top of the message (separated from the message body with a
blank line).
There must be exactly one message per file. Munpack cannot deal with
multiple messages in a single file, to decode things correctly it must
know when one message ends and the next one begins.
To decode a message, run the command:
munpack file
where "file" is the name of the file containing the message. More than
one filename may be specified, munpack will try to decode the message in
each file. For more information on ways to run munpack, see the section
"Using munpack" below.
Reporting bugs:
Bugs and comments should be reported to mpack-bugs@andrew.cmu.edu.
When reporting bugs or other problems, please include the following
information:
* The version number of Mpack
* The platform (Unix, PC, OS/2, Mac, Amiga, Archimedes)
* The EXACT output of any unsuccessful attempts.
* If having a problem decoding, the first couple of lines
of the input file.
Compilation:
The os2 sources have been compiled with IBM Cset++ version 2.1. The
makefiles "mpack.os2" and "munpack.os2" are for mpack.exe and
munpack.exe, respectively. Both makefiles also include statements to
compile the sources with EMX 0.9a from Eberhard Mattes.
Using mpack:
Mpack is used to encode a file into one or more MIME format messages.
The program is invoked with:
mpack [options] -o outputfile file
or
mpack [options] file address...
or
mpack [options] -n newsgroups file
Where "[options]" is one or more optional switches described below.
"-o outputfile" is also described below. "file" is the name of the
file to encode, "address..." is one or more e-mail address to mail the
resulting messages to and "newsgroups" is a comma-separated list of
newsgroups to post the resulting messages to.
The possible options are:
-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.
-f username
Specifies the user name to be used for mail or news. If
this option is ommitted, the environment variable LOGNAME
will be used to determine the user name.
The environment variables which control mpack's behavior are:
SPLITSIZE
Default value of the -m switch. Default "0".
HOSTNAME
Fully qualified domain name to use in generated message-ids.
Default "random-pc" or "random-amiga".
DOMAINNAME
If $HOSTNAME does not have a '.' in it, this is appended to
$HOSTNAME to get the domain to use. Default is
"random-domain".
POSTNEWS
Command to use to post news. Compatible with UUPC inews.
SENDMAIL
Command to use to send mail. Compatible with IBM sendmail.
LOGNAME
User name for sending mail or posting news. Defaults to
"postmaster".
Using munpack:
Munpack is used to decode one or more messages in MIME or
split-uuencoded format and extract the embedded files. The program is
invoked with:
munpack [options] filename...
which reads the messages in the files "filename...". Munpack may also
be invoked with just:
munpack [options]
which reads a message from the standard input.
If the message suggests a file name to use for the imbedded part, that
name is cleaned of potential problem characters and used for the
output file. If the suggested filename includes subdirectories, they
will be created as necessary. If the message does not suggest a file
name, the names "part1", "part2", etc are used in sequence.
If the imbedded part was preceded with textual information, that
information is also written to a file. The file is named the same as
the imbedded part, with any filename extension replaced with
".dsc"
The possible options are:
-f
Forces the overwriting of existing files. If a message
suggests a file name of an existing file, the file will be
overwritten. Without this flag, munpack replaces any
filename extension with ".1", ".2", etc to find a
nonexistent file.
-t
Also unpack the text parts of multipart messages to files.
By default, text parts that do not have a filename parameter
do not get unpacked.
-q
Be quiet--suppress messages about saving partial messages.
-C directory
Change the current directory to "directory" before reading
any files. This is useful when invoking munpack
from a mail or news reader.
-e
Writes the MIME content type into the extended attribute
"MIME-TYPE". This extended attribute can be used by any
software that post processes the decoded files. The
following is an example program how to read this extended
attribute in Rexx:
---------------------------cut here---------------------------------
/* This Rexx program demonstrates how to read the MIME-type *
* parameter out of the EA of the decoded file. Note, that the *
* options '-e' must be used to write this EA. */
call RxFuncAdd 'SysLoadFuncs', 'RexxUtil', 'SysLoadFuncs'
call SysLoadFuncs
parse ARG name
if SysGetEA(name, "MIME-TYPE", "TYPEINFO") = 0 then
parse var typeinfo 4 type
else
type = "undefined"
say "MIME content-type is" type
---------------------------cut here---------------------------------
The environment variables which control munpack's behavior are:
TMP
Root of directory to store partial messages awaiting
reassembly. Default is "\tmp". Partial messages are
stored in subdirectories of $TMP\parts\

PGP signature:
Starting with version 1.5, all official mpack distributions are PGP
signed by "John Gardiner Myers <jgm+@cmu.edu>". The PGP signatures
are detached from the distributions themselves, in files with the
".asc" filename extension. If the location where you obtained mpack
does not include the PGP signature, or if the signature is not valid
for the distribution, please complain to the maintainer of the
relevant distribution site.
A valid PGP signature indicates that the distribution is the one that
I put together; it specifically does not indicate any warranty of any
kind on the software. The Unix and DOS versions were done by myself,
the DOS binaries were checked for viruses using an up-to-date virus
checker. The Macintosh version was done by a colleague I have reason
to trust. All other versions were done and compiled by people I have
had no personal contact with.
