  For a long time, everybody used Huffman compression.  Then Lempel-Ziv
(which I presume is a recent development) became popular, and everybody 
started using that instead.  Now I see a return to Huffman, and some 
utilities which claim to use some sort of combination.

  Could somebody please explain all this to me?  Which is better for what?
Can they really be combined?  Why are people returning to Huffman
compression?
