I'm not sure why you think that. The only kinds of archives whose
file types are ambiguous from the name, are sdist, bdist_dumb, and
random raw source dumps. Everything else has a unique extension like
.egg, .exe, .msi, rpm, etc. If you have a .zip, .tar.gz, .tgz, or
some other archive name, you can find out if it's an sdist by
inspecting its contents as I described. And if it's not an sdist, you
can usually tell if it's a raw source dump by checking for a setup.py
in the archive root or a depth-1 subdirectory off the root. (That's
what easy_install does, anyway, when it's given an archive it doesn't
know what to do with.)
