Yes, several.  :)  find_distributions() by default finds *all* 
distributions in the directory, and there is no guaranteed order to the 
results.

Even if you pass the 'only' flag to tell it to just find distributions 
whose 'location' would be the same directory, you can *still* have more 
than one result in the case of system-packaged 
(--single-version-externally-managed) eggs, as they all end up in the same 
directory.

There is no reliable way to tell what distribution you are in, if all you 
have is the directory name.  If you have a *module* name, however, you can 
use get_provider(modulename).get_metadata('PKG-INFO') to retrieve the 
package's PKG-INFO text, which you can then use to find the distribution 
name and version.
