Program UnSQueeze;       Unsqueeze file from in_file to out_file.

    This program unsqueezes a file which has been squeezed or compressed
to reduce the space required to store it on disk.  The program was
converted from the original version written for CP/M in the C language.
This program can be used to unsqueeze files which have been downloaded
from RCP/M systems where almost all files are saved in this squeezed
format.

    The technique used is the Huffman encoding technique which converts
the most common characters in the input file to a compressed bit stream
of data.  This program unsqueezes such a Huffman encoded file.

  Version 1.0  - 09/05/82  Scott Loftesness
  Version 1.1  - 01/06/83  Added capability to strip off parity bit if
                           output file is text.  Ernie LeMay 71435,730
  Version 1.2  - 07/20/84  converted to Turbo Pascal.  Steve Freeman
  Version 1.3  - 10/15/85  converted to Turbo Pascal 2.0  Bob Moss
                           added getbuf, putbuf, putc - changed getc
                           to provide buffered I/O.(128 char buffer)
  Version 1.4  - 09/15/87  added a CP/M dir program that will first
                           display a directory to allow the user to
                           decide on which file to use.  Also changed
                           the ClrScr statement since some computer
                           operators don't know the ASCII call to do
                           this or sometimes ClrScr doesn't work.
                           Added number counter so that the user knows
                           it's doing something.  Also added High/Low.

  Version 1.4.1 - 09/17/87 Opps, the uppercase doesn't seem to want
                           to work all the time so I took out calls
                           made durring the UNSQUEEZ-IT WORKING
                           screen.  Well, looks like you will have to
                           wait till 1.5 comes out when I will then also
                           have it add file input at the CP/M prompt.  I
                           also have the ASM code source for USQ and so
                           version 1.6 will have inline source for anyone
                           using the Ziolog 80 chip.  Ta ta for now.
