No problems about that. I think that some unittests could do part of
that work as well. Once it gets into the standard library it will be
exposed and may be extensively tested.

I'd rather choose a default interface similar where possible to that
of zipfile. This makes it easy to include support to tar.gz in programs
already supporting zipfile, and also creates some standardization. I'm
including python-dev in the discussion to know what they think about

I can help you in any of those tasks, if you need.
I've just submitted a patch to include mknod() in posixmodule. This
will make it easy to include the missing support for special device files.
You have implemented the most important GNU extensions (long filenames),
and mention you'd like to implement others. OTOH, I've read in the tar
documentation that some of the extensions may change until tar 2.0. This
would turn into a bad option implementing them right now, IMO. What's
your opinion about this?
You mention in some document that one of the differences between tarfile
and tar is that tarfile uses relative path names. Isn't that the default
behavior of tar as well, which could be changed by the -P parameter?

Don't worry.. we're not in a hurry. :-)

Thank you very much!
