Note that relative to a *Python package name* isn't quite as useful, 
due to namespace packages.  To be unambiguous as to the targeted 
resource, one needs to be able to reference a specific project, and 
that requires you to go off the name of a module *within* a 
package.  For example, 'zope.somemodule' rather than just 'zope'.  To 
put it another way, you don't want to use a module that comes from an 
__init__.py as your origin point, but rather, some other .py file 
within the package.  Then you can talk to that module's loader 
without fear of ambiguity.

"isdir" and "exists" would also be nice; pkg_resources provides 
those, plus listdir and string/stream.
