**  Version 1.00 - by D. Clarke 22/07/94
**
**  Searches a file for the Amiga version string
**  and prints out the information found. This is
**  useful for checking the versions of programs
**  downloaded onto machines other than the Amiga.
**
**  The source has been compiled under both MS-DOS
**  and Unix (DEC3100). I can't see that there
**  should be any problems in compiling the code
**  under any other operating system as it is pure
**  ANSI C. If any problems are found I can be
**  contacted at the following E-Mail address until
**  the end of September 94 :

**  	p9365141@athmail1.causeway.qub.ac.uk
**
**  The code is Copyright (c) 1994 by D. Clarke.
**  However feel free to make any enhancements you
**  wish. I just don't want people changing the
**  code and leaving my name on it (so I get blamed
**  for their mistakes as well as my own!). If you
**  do make any improvements, I would appreciate a
**  copy.
