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.
