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

# Variables:
#	model
#	MODEL (uppercase version of "model"; toupper is not portable)
#	echo (yes iff we will show the $(CC) lines)

#
# Fields in src/modules:
#	$1 = module name
#	$2 = progs|lib|c++
#	$3 = source-directory
#
# Fields in src/modules past $3 are dependencies
