why bzip2 is still used.

grzip from ports (archivers/grzip) is much faster and compresses much 
better and it's not GNU licenced

html is all html files from /usr/share/doc libs.tar is from my
/usr/local/lib/*.so.*, and mail.tar are all FreeBSD mailing lists mails 
i've got tarred.

i run gzip -9, bzip2 -9, grzip -m3 -b8m, rar -mdG -m5.

rar is almost clear winner (2-cond with mail compression), but clear loser 
on speed and it's closed source.

excluding rar, grzip is a clear winner. the differences are large.
