# -----------------------------------------------------------------------------
# Examples of use:
#
# 	make		-- run all the tests in the current directory
# 	make verbose	-- as make test, but up the verbosity
# 	make accept	-- run the tests, accepting the current output
#
# The following variables may be set on the make command line:
#
#	TEST		-- specific test to run
#	TESTS		-- specific tests to run (same as $TEST really)
#	EXTRA_HC_OPTS	-- extra flags to send to the Haskell compiler
#	EXTRA_RUNTEST_OPTS -- extra flags to give the test driver
#	CONFIG		-- use a different configuration file
#	COMPILER	-- select a configuration file from config/
#       THREADS         -- run n tests at once
#
