Paul, Paul, Paul.... :)

The compression routine works for lzss compressed data.  It knows
nothing about STEP.  If the STEP module used the prescribed lzss
compression, then it should work :)

Obtuse!?!??  :)  I thought the API was clever 3 years ago! :)  It's
really not that bad in my opinion.  It gives you some options that might
not be intuitive, like subclassing and overriding only a few methods to
make it work against other datasources besides string buffers, but you
don't HAVE to use these if you don't want to.  The simplest use is:

SWCompress *compression = new LZSSCompress();
compressedText = compression.zBuf();


plainText = compression.Buf();

Now that's not TOO OBTUSE is it?!

Change the above line in the example:

-SWCompress *compression = new LZSSCompress();
+SWCompress *compression = new ZipCompress();

You can make a BZipCompress::SWCompress for us if you really want to.
