# `_pandemoniummonium` module contains all the callbacks needed by Pandemonium's Pluginscript
# system to expose Python as a language to Pandemonium (see pythonscript.c for
# more on this).
# Hence there is no point of importing this module from Python given it
# only expose C functions.
# Beside this module depend on the `pandemoniummonium.hazmat` module so it would be a bad
# idea to make the `pandemoniummonium` module depend on it...
