Unclear how to setup a C project using genfiles

[oliversheridanmethven]

I have a project which has the following structure

my_project/
- stuff...
- src/
   - arv/  # <-- A C library with .c and .h files. 
   - pyarv/  # <-- A python binding of the C library, also with .c and .h files. 

I am trying to get all the .c and .h files documented using this tool. I have a draft gen file for makedocstring (which I've converted from my Python version to the C version), but I can't get it up and running as expected. The current state of my code can be found here: oliversheridanmethven/pyarv#27 (it's a real project, so quite messy and not minimal).

Could you provide some more documentation about how to write a generation script to take the source and header files and glue it all together?
