3# Unit tests for make(1)
4# The main targets are:
5# 
6# all:	run all the tests
7# test:	run 'all', capture output and compare to expected results
8# accept: move generated output to expected results
9#
10# Adding a test case.  
11# Each feature should get its own set of tests in its own suitably
12# named makefile which should be added to SUBFILES to hook it in.
