function_doc_signature_generatorfunction_doc_signature_generator synopsisBoost.Python supports docstrings with automatic
appending of Pythonic and C++ signatures. This feature is implemented
by class function_doc_signature_generator
The class uses all of the overloads, supplied arg names and default values, as well as
the user-defined docstrings, to generate documentation for a given function.
function_doc_signature_generatorThe class has only one public function which returns a list of strings documenting the overloads of a function.
