* What is it

A basic implementation of the LZW compression algorithm, all in Emacs Lisp.
The code has not been optimized, and I welcome any improvements.  As it is,
the resulting conversion of a large Lisp form to a base64-encoded string,
using `lzw-compress-data', achieves a compression ratio near 50% over just
turning the data into a string with `prin1-to-string'.

* Where to get it
