Why update_config() in config.py won't add default paths to config if no modulename param?

[sebe...@spawar.navy.mil]

I was looking at source of update_config in turbogears/config.py.

**ONLY** when a modulename param is passed does the config receive
standard default paths such as top_level_dir, package_dir &
current_dir_uri.

Can someone please explain, if they don't mind, why when NO modulename
param is passed does poor little config **NOT** get those nice paths
defined like top_level_dir, package_dir & current_dir_uri?? :)

Thanks,

Chris

This is a fine question. top_level_dir and package_dir are both based
on the module specifically (they use the
pkg_resources.resource_filename which locates things relative to the
pythonpath).

current_dir_uri could be defined in all cases, though.
