-- Compile files into pgf, in chosen combinations.

-- Usage: runghc Compile (-make | -link)? Eng Fre Fin ...
-- The -make option links all pgf files to one in the end
-- The -link option only links, without first compiling
-- Arguments whose length are 3 characters are prefixed with mainmodu.
-- Other arguments are passed literally.

-- Thus, for instance, to produce an English-Swedish-Romanian phrasebook with English
-- disambiguation, the command is
--
--  runghc Compile -link Eng Swe Ron DisambPhrasebookEng


-- change this to apply to another project; alternatively, just use full file names
