/usr/share/gtk-doc/python/gtkdoc/__init__.py
I think these python files are meant as example code for incorporation into other projects. If so, compiling them makes no sense.
I think they are gtk-doc itself now e.g. from /usr/bin/gtkdoc-scan ``` try: import gtkdoc_uninstalled except ModuleNotFoundError: sys.path.append('/usr/share/gtk-doc/python') from gtkdoc import common, config, scan ```
