It might be nice to note in the description that 7-zip does better
compression than pkzip and other archivers for the .zip archive format.

Obviously so, because it can handle RAR archives. The only RAR archiver
that we have in Debian is in non-free. 7-zip is GPL'd, IIRC.

http://www.compression.ca has some comparisons. I would guess that it is.
I don't know if it's provable. Another site for 7-zip is
http://www.7-zip.org which indicates that 7-zip's zip format compresses
files to be smaller than both pkzip and winzip. I suppose "better" should
be qualified as meaning creating smaller files as compression time is an
indicator too.

Has anyone contacted Charles Bloom about relicensing PPMZ2? It may offer
"better" compression than the 7z format.

Has the author of 7-zip been informed as to this ITP?
