+The package that provides generating methods for all parts

 Currently, these are hardcoded as strings. It would be possible
 to switch these to cgen expression. OTOH, there is not much to be
 gained there.

+NB: Previously this __init__.py was a module driver.py. As it was growing,
+    we made it a package. Some content could and should be separated into
+    new modules within this package!
