Comment 1 for bug 1383510

This is probably the biggest PITA of whole cloud-init. I'm amazed that nobody cared enough to put at least a bit of a documentation out in the world. No wonder people are angry about this project, geez. Not everybody wants to read the code to understand how it's working...
I'll try to do some basic documentation for most of the modules. Once it gets there it should automatically pop up in RTD by the include (automodule) in doc/rtd/topics/modules.rst.
