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

/* HISTORY
 * 27-Sep-90  Richard H. Gumpertz (rhg@cps.com)
 *		add check for EXTERNAL_GETOPT to suppress the built-in getopt.  (The
 *		builtin getopt is nice because it makes unshar more easily portable.)
 * 12-Sep-90  Richard H. Gumpertz (rhg@cps.com)
 *		use fprintf instead of printf when printing error return from getwd.
 *		deleted unused initialization of more_to_read in process.
 *		changed ch from char to int in process so the EOF check would work.
 *  4-Aug-90  Richard H. Gumpertz (rhg@cps.com)
 *		renamed -c and -C to -e and -E and added -c flag (passed through to sh)
 * 24-Apr-90  Richard H. Gumpertz (rhg@cps.com)
 *              rewrote ENC() to use a more efficient formula
 * 19-Apr-90  Colas Nahaboo (colas@mirsa.inria.fr)
 *		added -c and -C flags to read from concatenated archives
 *  1-Feb-85  Guido van Rossum (guido@mcvax) at CWI, Amsterdam
 *		Added missing 'quit' routine;
 *		added -d flag to change to directory first;
 *		added filter mode (read stdin when no arguments);
 *		added 'getopt' to get flags (makes it self-contained).
 * 29-Jan-85  Michael Mauldin (mlm) at Carnegie-Mellon University
 *		Created.
