-- Make commands for compiling and testing resource grammars.
-- usage: runghc Make ((present? OPT?) | (clone FILE))? LANGS? 
-- where 
-- - OPT = (lang | api | math | pgf | test | demo | clean)
-- - LANGS has the form e.g. langs=Eng,Fin,Rus
-- - clone with a flag file=FILENAME clones the file to the specified languages,
--   by replacing the 3-letter language name of the original in both 
--   the filename and the body
--   with each name in the list (default: all languages)
-- With no argument, lang and api are done, in this order.
-- See 'make' below for what is done by which command.

-- the languages have long directory names and short ISO codes (3 letters)
-- we also give the decodings for postprocessing linearizations, as long as grammars
-- don't support all flags needed; they are used in tests
