I have used gr_modtool to add custom blocks in python to an OOT module. It appears that all the source python I write must reside in the gr-my_oot_module/python directory.
I will be writing a lot of code spread over many python files. I would like to organize those files into sub-directories (presumably) under gr-my_oot_module/python. Simply creating those directories and putting code there does not lead to a successful build.
What is the correct approach to organizing the python files I write for this module into sub-directories?
