Oops didnt see this msg ... AFAICR ... this is the kind of reasons
ResourceManager is there for in pkg_resources ... CMIIW anyway ...

However GvR was talking about PEP 302 loaders ... well ... the only
thing I can say is that bundling message catalogs in egg files (they
'r zip files anyway ;) and using them with Babel (... similar to
gettext ... I think ...) works fine for me using the aforementioned
functions in pkg_resources ... About whether PEP 302 loaders should
(look like | implement functions in) pkg_resources.ResourceManager or
not ... I'm not very sure ...

... and I'm talking about ...

{{{
>>> [x for x in dir(pkg_resources) if 'resource_' in x]
['resource_exists', 'resource_filename', 'resource_isdir',
'resource_listdir', 'resource_stream', 'resource_string']

}}}
