web tool help

[s.t. bischoff]

there is a fellow working on a non-commercial toolkit that improves on some
of the xfst/lexc stuff. the major difference is simplified notation for
things like reduplication, unification, long distance dependencies, free
morpheme order, etc. The flag system seems a little combersome in the xerox
kit, and this free kit will do away with them entirely. hopefully it will be
available soon, though the xerox kit works remarkably well. Karttunen (one
of the authors) says that "phonology and morphology are solved"...as more
people work with this fst technology we'll see.

thanks for the advice.
