+% Before \TeX Live 2013 version, \LUATEX had a bug that made ofm fonts fail
+% when called with their extension. There was a side-effect making ofm
+% totally unloadable when luaotfload was present. The following lines are
+% a patch for this bug. The utility of these lines is questionable as they
+% are not necessary since \TeX Live 2013. They should be removed in the next
+% version.

+% work. However they do not seem necessary so they are commented for now.
