Description: This is a little console mode utility program which is able to
(de-)compress single files with a static Arithmetic compression
algorithm. You could easily add the RLE/BWT/MFT data
transformation algorithms. Just rip the corresponding classes
out of my HuffComp source code. I won t add these ones in the
next time.-This is a little console mode utility program which is able to (de-) compress single files with a static Arithmetic compression algorithm.
