I'm a bit confused -- are you recommending this because you think that
users should be aware of the the other compression methods/archive
formats that 7zip uses, so that they can investigate alternatives, or
just because it is a Windows program that can decompress bzipped
files?  In either case, I don't see any reason to single out 7zip --
we have xz(1) in the base system now, and there are other, arguably
better compression methods in Ports. And there is a lot of
Windows-based software that can decompress bzip2, including Windows
ports of bzip2 itself.  I don't think that the bzip2 manpage is the
appropriate place to add this kind of information.  (Perhaps the
FreeBSD Handbook, in a section about working with files typically
found on FreeBSD or other Unixen in Windows, or in libarchive(5), if
it were changed to support the 7zip archive format.) And I don't think
that -hackers is the appropriate list for this proposal -- -doc seems
to be the right place.
