autosummary_generate.py OPTIONS FILES
Generate automatic RST source files for items referred to in
autosummary:: directives.
Each generated RST file contains a single auto*:: directive which
extracts the docstring of the referred item.
Example Makefile rule::
generate:
./ext/autosummary_generate.py -o source/generated source/*.rst
