###############################################################################

# This file contains definitions and descriptions of the variables used
# in the CLAM system (Coordinated Library Automagic Make).  This defaults
# file should be included near the start of the user's makefile, and then the
# rules file should be included after the user has modified the appropriate
# variables and added the appropriate rules and targets.
