RAR is a proprietary format, which complicates things. For example,
Linux distributions like Debian cannot distribute software which
handles it. If Python included such a module, they'd be forced to
remove it from their version.
I wouldn't encourage its use by writing /more/ software which handles
it. IMHO, archives should be widely readable forever, and to be that
they need to be in a widely used, open format.
