Please note, this package is no longer being maintained. CONS is a replacement for 'make.' It is not compatible with make, but it offers features not found in make or other build tools including:

  • integrated dependency analysis (no more "make depend" to generate static lists of .h files)
  • complete, non-recursive dependency analysis across multiple directories;
  • multiple side-by-side variant builds;
  • compilation from MD5 signatures instead of time stamps for determining whether a file is up-to-date
  • extensibility via Perl.

CONS is implemented in Perl. You don't need to know Perl to use CONS, although you can use it more powerfully if you do.
