+========
+
+Sphinx extension that handles docstrings in the Numpy standard format. [1]
+
+It will:
+
+- Convert Parameters etc. sections to field lists.
+- Convert See Also section to a See also entry.
+- Renumber references.
+- Extract the signature from the docstring, if it can't be determined otherwise.
