Check locally installed packages against one or more package indexes for updates and list them. Using subprocess instead of stdout (wasn't working on my MacPython 2.6.1)
#!/usr/bin/env python
Use pip to get a list of local packages to check against one or more package
indexes for updated versions.

Call pip's freeze -l
returns a list of package_name, version tuples

out, err = process.communicate()
pkgs = out.split('\n')

def find_current_version(package, index_urls=None):
Using the XMLRPC method available for PyPI, get the most recent version
of <package> from each of the index_urls and figure out which one (if any)
is higher
Returns a tuple of the index with the higher version and the version it has

Compare 2 versions, starting with StrictVersion, and falling back on
