- In the GNU bulletin I see that a replacement for compress
- is wanted. I have studied some data compression techniques,
- mostly variants of lz and huffman + some aritmetic coding.
- I have even written a program that compress better than
- compress, although it is too slow to be of much use.
- (It even compressed files compressed by compress some 1-3%)
-
- .....
-
- Speed, compression ratio, non-patented, how good must it be?
-
- Is a program with about the same capabilities as compress,
- but without any known (to me) patents good enough?
-
- I think a variation on huffman coding could be both fast
- and good enough, but how many variations on huffman coding
- are patented?

- [mod- I was under the impression that Huffman coding was not patents,
- but dont quote me on this...]
