def distributions_with_commands(ws=pkg_resources.working_set):
     for dist in ws:
         if dist.get_entry_map('paste.script_command'):
             yield dist


Distribution.get_entry_map() returns a dictionary mapping entry point names 
to EntryPoint objects, so this code yields the distributions on sys.path 
(by default) that contain any entry points in the 'paste.script_command' group.
