sphinx.ext.autosummary.generate
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Usable as a library or script to 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:
sphinx-autogen -o source/generated source/*.rst
