This looks like a standard compression method, but what I was thinking
of was more along the lines of an English dictionary. Perhaps the
program would search the file(s) to be compressed and compile a "common
word list." No doubt all compressors use this technique to some extent,
but it seems that one would get much better compression on plain text
files (i.e. written documents) if the compressor knew that this is what
it was squishing.
