p7zip is the Unix port of 7-Zip, a file archiver
that archives with very high compression ratios.

p7zip provides /usr/bin/7zr, a standalone minimal
version of the 7-zip tool that only handles 7z archives.
It also provides /usr/bin/7za, a statically-linked
application that supports packing and unpacking 7z,
zip, gzip, bzip2, and tar archives.  Additionally, it
provides /usr/bin/7z, a module-based application that
supports the full set of 7-zip compression formats:
  pack/unpack: 7z, zip, gzip, bzip2, tar
  unpacking:   arj, cab, chm, cpio, deb, dmg, hfs, iso, 
               lzh, lzma, msi, nsis, rpm, udf, wim, xar,
The modules used by 7z are located in /usr/lib/p7zip/.

RAR unpacking support is NOT provided, as the UnRAR license
not OSI-approved and is incompatible with cygwin. You are
free to download the source package and rebuild p7zip *for
your own personal use* as long as you do not distribute the
resulting binary, if you need RAR unpacking support.

[[ compiled using gcc-3.4.4-999 and g++-3.4.4-999 ]]

This will most likely be the final p7zip update for the
cygwin-1.5 distribution; future development will continue
with p7zip-4.65-10 for cygwin-1.7.
