# The following parameters may need to be set for the target machine:
#    TRAP_PATH - the path to the trap.handler file
#    TOP_DIR - where to find X stuff
#    MY_LEX - needed only if you want to change the scanner (scanner.l)

#
# To make spim, type:
#
#   make spim
#
# To make xpsim, type:
#
#   make xspim
#
# To verify spim works, type:
#
#   make test
