There is a section in the docs that describe config-lang.in. Try looking at it. Also, try looking at the config-lang.in files for other language front ends. As for makefile.in, well, try reading some documentation on the "make" program. Try "info make". -- Jim Wilson, GNU Tools Support, http://www.SpecifixInc.com
