X *    I have made several mods to this program:
X *
X *    1) the -----Cut Here-----... now preceds the script.
X *    2) the cat has been changed to a sed which removes a prefix
X *    character from the beginning of each line of the extracted
X *    file, this prefix character is added to each line of the archived
X *    files and is not the same as the first character of the
X *    file delimeter.
X *    3) added several options:
X *        -c    - add the -----Cut Here-----... line.
X *        -d'del' - change the file delimeter to del.
X *        -s    - cause the resulting script to print the wc of
X *              the orignal file and the wc of the extracted
X *              file.

X *    I, too, have been hacking this code. This is the version on sixhub
X *        bill davidsen ([e-mail])
X *
X *    - added support for binary files
X *    - automatic creation of limited size multiple file archives,
X *      each of which may be unpacked separately, and with sequence
X *      checking.
X *    - support for mixed text and binary files
X *    - preserve file permissions
X *    - restore to filename rather than pathname
