Glad I could return the favor. :)
Since then, I took it a bit further for use in my code... I am not finished
with it yet, but am curios what you think. (I am not sure named things right
or structured it logically....)

class HomePath(object):
"""For finding paths based on a home/install directory.
"""
def __init__(self, home_dir = None, home_file = None):
"""Must be called with either a path to a directory or, as a
shortcut, a file in that directory.

if home_file != None:
# Set home based on a path to a file in its directory
self.home = os.path.normpath(self.fix_path(home_file))
elif home_dir != None:
# Set home based on its path
self.home = os.path.normpath(self.get_dir(home_dir))
else:
raise Exception("Must call with either a path to a directory
or, as a shortcut, a file in that directory.")

path)))
