Building help resources from the combined interlingua corpus (2)

Considerable progress on this task today:

1. I've added French to the AFF interlingua corpora, including the New York material as requested by Pierrette. The corpora are remade and checked in.
2. The help resources for Eng and Ara (the languages where we have help class definitions) are now made from the combined interlingua corpus. A separate help file is made for each of the six pairs EngAra, EngFre, EngJap, AraEng, AraFre, AraJap, reflecting the different levels of coverage. You can make the help resources for all of these pairs by doing 'make help_resources' in $MED_SLT2 (i.e. at the top level in the MedSLT directory), and it only takes a few minutes.
