The 2 backends, mg and mgpp, use independent code (even though I think both
sets of code are identical for the stemmer).

For example, look in
gsdl/src/mgpp/lib/simplefrenchstem.cpp
gsdl/src/mgpp/lib/lovinstem.cpp
for the stemmers,
gsdl/src/mgpp/text/stemmer.cpp
for the code that decides which stemmer to pass words to.
