mod.__name__  gives the module name, and   mod.__file__  gives the full 
path to the given module.  Or if you need those for the current module, 
just leave off the prefix.

For line number information, you probably can get it from the inspect 
module, but I don't have any direct experience.  I do have the following 
untested line
in my notes:
           inspect.getframeinfo(inspect.currentframe()).function)
