+# Gnumeric has two python components
+# 1. The python loader for loading python-based plugins.
+#    This component is pure python 2 and a port "is not currently being worked on".
+# 2. The python gobject-based introspection API. This component is compatible
+#    with python 3.
+# Component 1. can only be re-enabled once someone has ported the upstream
+# codebase to python 3.
