The parse grammar Parse8.pgf for 8 languages can now be built in parallel with
make -j. Finnish requires a lot of RAM. French requires a lot of time.
Other related make targets available for convenience:
make Parse: create Parse???.pgf for the 8 individual languages
make Parse8: create Parse8.pgf assuming all Parse???.pgf already exist
Note: these make targets (and some others) use the gf executable and RGL
library that are installed on the system (found via $PATH and $GF_LIB_PATH,
respectively).
