##  Makefile.rules -- simple generic SystemC example build rules
##
##  Include this file from your own Makefile to obtain a simple build
##  environment.  You need to set at least the variables
##    PROJECT - name of the application
##    OBJS    - list of required object files
##  to make things work.
##
##  The environment is assumed to be set up from Makefile.config file and
##  the main example Makefile.
