/* The boo and de-boo programs do not work, and I found them too cumbersome
* and complicated to install on the DG. In their place, I have provided
* a few other tools:
*
* uuencode and uudecode:
* Convert any binary file to a non-binary file, and preserve the
* DG record and file types, if done on DG systems.
* sq and usq:
* CP/M (and others) squeeze and unsqueeze programs. Should be
* compatible with Unix and other hosts.
* compress:
* a more efficient compression than sq/usq. Also compatible with
* many hosts.
*
* If anyone can get these other files working, more power to you. The
* uudecode program is slow, but the squeeze programs are very fast. The
* uudecode could be faster, but I did not want to wasted alot of time on
* it. Anyway, the uudecode source is very simple, and should be easy to
* convert to another language. If you do convert the uudecode program,
* please let me know, so that it can be distributed to hosts that do not
* have the C compiler.

/*
* MSBPCT.C
*
* Howie Kaye -- Columbia University 3/11/86
*
* sibling program to MSBMKB.C. It is used to unpack BOO files, used for
* encoding binary files into text, and back. This program does the decoding.
* It is meant to replace the program "MSBPCT.BAS", and runs approximately
* 200 times faster.
*
* For documentation on BOO file format, see MSBMKB.C
* This program runs, as is, under Microsoft C on MSDOS, and under UNIX(4.2).
*
* Modification history:
*
* 3/23/86 - Davide P. Cervone -- University of Rochester
* added AMIGA and VAX11C support
*
* 3/24/86 - Martin Knoblauch -- TH-Darmstadt (MK001)
* test if 1. line of inputfile is delimited by "\r\n" instead of "\n"
*
* 5/5/86 - John Matthews, U of Delaware.
* Explicitly close the files.
*
* 5/8/86 - L. John Junod, DTNSRDC.
* Adapt for Computer Innovations MS-DOS CI-86 Compiler
* Improve too many args error message
