32# Generate compile-rules for the modules that we are using in libraries or
33# programs.  We are listing them explicitly because we have turned off the
34# suffix rules (to force compilation with the appropriate flags).  We could use
35# make-recursion but that would result in makefiles that are useless for
36# development.

38# Variables:
39#	model

45#	$1 = module name
46#	$2 = progs|lib|c++
47#	$3 = source-directory
