While on this bit of code, this also will not work if Apache was run as
a user which had write access to the directory the files are in. This is
because in that case, Python will be able to write ".pyc" files to the
directory and thus the "__file__" attribute may actually have a ".pyc"
suffix and not ".py". Thus appropriate use of os.path.splitext() may be
in order rather than assuming that ".py" extension will always be used.
