"""Print the metadata for one or more Python package distributions.
Usage: %prog [options] path+
Each 'path' entry can be one of the following:
o a source distribution: in this case, 'path' should point to an existing
archive file (.tar.gz, .tar.bz2, or .zip) as generated by 'setup.py sdist'.
o a binary distribution: in this case, 'path' should point to an existing
archive file (.egg)
o a "develop" checkout: in ths case, 'path' should point to a directory
intialized via 'setup.py develop' (under setuptools).
o an installed package: in this case, 'path' should be the importable name
of the package.
