Reports I have seen indicate a savings of FIVE MEGABYTES on Where can I get a copy of the ZIP file format and compression algos? Are the format and compression algorithm public-domain? Does PK promise he won't change the format on us, so we don't end up with the old problem of PKZIP ver n-1 being unable to read files made by PKZIP ver n? Is the compression really significantly better than Lempel-Ziv? What restrictions does PK place on using his stuff? Money for the code? Money for using the format? Is the source part of the standard distribution, so we can find out what it "really* does? Is the format ASCII, or binary? Somebody else recently posted an article about a new ascii-to-binary packer, I think Brad Templeton. -- # Bill Stewart, AT&T Bell Labs 2G218 Holmdel NJ 201-949-0705 ho95c.att.com!wcs # Synchronicity is when the paper has an article about Moonie ties to # Right Wing Politicians, and they're dropping the charges against Ollie North, # and you finally find that copy of "Illuminatus!"
