What I have done is transcribe the LZHUF algorithm into Turbo pascal.
LZH.PAS is the source code for a fairly flexible unit which can compress and
decompress any kind of datayou throw at it. LZHTEST.PAS is a sample program
which can compress/decompress one file at a time.
What you see is what you get - little documentation, moderate performance
(be charitable, please), and it's free. Enjoy.

There was a bug in the first version I made available in February which
caused the unit to hang if it was called upon to compress a large amount
of data. I have fixed this one bug and it now seems to work correctly.
I apologize for any lost sleep this may have caused.
