/*
* 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.

/*
* I, too, have been hacking this code. This is the version on sixhub
* bill davidsen (davidsen@sixhub.uucp)
*
* - added support for binary files
* - automatic creation of limited size multiple file archives,
* each of which may be unpacked separately, and with sequence
* checking.
* - support for mixed text and binary files
* - preserve file permissions
* - restore to filename rather than pathname
*
*/
/*
* One good hack deserves another ... this version generates shell
* code which attempts to create missing directories
* handle deviants sun, vax, pyr (pyramid), SCO XENIX/UNIX automatically
* for sequent, add -DBSD42
* force Verbose on
* if unsharing system's touch Sys V compatible (allows touch -m),
* restore file dates
* -n switch puts an alpha "name" in header
* -a (if also -n) puts "Submitted-by:" & "Archive-name: <name>/part##
* use getopt
* as well as some other chrome-plated junque

char RCS_ID[] = "$Header: /u/rhg/src/shar/unshar.c,v 3.51 90/09/27 19:45:58 rhg Exp $";
/* 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.
