"""genpy.py - The worker for makepy. See makepy.py for more details
This code was moved simply to speed Python in normal circumstances. As the makepy.py
is normally run from the command line, it reparses the code each time. Now makepy
is nothing more than the command line handler and public interface.
The makepy command line etc handling is also getting large enough in its own right!
"""
# NOTE - now supports a "demand" mechanism - the top-level is a package, and
# each class etc can be made individually.
# This should eventually become the default.
# Then the old non-package technique should be removed.
# There should be no b/w compat issues, and will just help clean the code.
# This will be done once the new "demand" mechanism gets a good workout.
