CHANGES:

------------------------------------
March 1, 2005 - Version 1.1 Released

Added a test to make sure the file is a bit-mapped graphic file
before proceeding to do the conversion. If not, an error message
is written and the program terminates.

Beefed up the error reporting to specify the file name being
processed to make life easier when running a script to convert
multiple files.

Fixed an error reading the mode data from the input file.  The
variables which were being read incorrectly would have no effect
on the conversion of bit-mapped graphic files, but it's good to
do it right.

If the program is invoked with no arguments, now the version info
along with the usage will be printed.

The program is still limited to one vertical tile.
