- : How about storing them as GIF's, which are inherently compressed using
- : the LZW algorithm (the one used by compress).

- There's a few disadvantages to using GIF format. Most namely is the
- restriction to 256 colors.

- What kind of compression technique do those
- programs [stacker/doubledisk/etc] use? (Hopefully this isn't the start of
- a completely unrelated discussion) ... The only thing that I think gets
- really ugly about those programs if you have a file that contians a block
- of zeros in the middle, then you have a program that fseeks to that block
- and writes a block of random data over it. The compression program has
- to deal with expansion in the physical file size.
