3# Unit tests for make(1)
4#
5# The main targets are:
6#
7# all:
8#	run all the tests
9# test:
10#	run 'all', and compare to expected results
11# accept:
12#	move generated output to expected results
13#
14# Settable variables
15#
16# TEST_MAKE
17#	The make program to be tested.
18#
19#
20# Adding a test case
21#
22# Each feature should get its own set of tests in its own suitably
23# named makefile (*.mk), with its own set of expected results (*.exp),
24# and it should be added to the TESTS list.
25#
26# Any added files must also be added to src/distrib/sets/lists/tests/mi.
27# Makefiles that are not added to TESTS must be ignored in
28# src/tests/usr.bin/make/t_make.sh (example: include-sub).
29#
30
31# Each test is in a sub-makefile.
32# Keep the list sorted.
