No, since it relies on a package (bzrlib) that's not in the stdlib or 
bundled with setuptools.

You can, however, just add a setup.py to your module that declares 
the entry point, and upload the whole thing to Cheeseshop.  You can 
even declare its dependency on bzrlib and have that automatically 
installed too, assuming that it's either on the Cheeseshop or you can 
supply a download link or page with download links in your 
setup(find_links=[...]).

Well, the assumption is that only the plugin knows whether a 
directory is a candidate for recursion.  Also, some revision control 
systems only keep path information in one place, so trying to call 
the plugin recursively would be redundant.

Fair enough; patches welcome.  In fact, feel free to just go ahead 
and check documentation additions right in, just drop me a line and 
let me know what you did so I can double-check and edit if necessary.
