# Unit tests for make(1)
# The main targets are:
# 
# all:	run all the tests
# test:	run 'all', capture output 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 which should be hooked
# into the 'all' target.
