+    \return   None
+    \brief    What would an SVG editor be without loading/saving SVG
+              files.  This function sets that up.
+
+    For each module there is a call to Inkscape::Extension::build_from_mem
+    with a rather large XML file passed in.  This is a constant string
+    that describes the module.  At the end of this call a module is
+    returned that is basically filled out.  The one thing that it doesn't
+    have is the key function for the operation.  And that is linked at
+    the end of each call.
