# Unit tests for make(1)
# The main targets are:
# 
# all:	run all the tests
# test:	run 'all', and compare to expected results
# accept: move generated output to expected results
#
# Adding a test case.  
# Each feature should get its own set of tests in its own suitably
# named makefile (*.mk), with its own set of expected results (*.exp),
# and it should be added to the TESTNAMES list.
