I'm looking for a package that will automatically detect the type of and extract an archive (zip, tar.gz, etc). In Perl, this is easy - in Python, I can't find any simple package/class to do it...
Riding off of Mark Byers' response, perhaps you can tie all of these together with mimetypes (also from the standard library). You could identify the type of file, and process it accordingly. The world needs a Python version of Archive::Extract, and we want you to write it!
