splitcf is a program that is very valuable when dealing with large FORTRAN and C codes. Often, valuable legacy codes are inherited with little or no documentation or organization; splitcf can reorganize the files, create documentation, construct the dependency table, create Makefiles, and so forth. It can deal with code that cannot compile or is ambiguous, and is in use both at TJNAF and NASA/LaRC.
