1# $NetBSD: opt-m-include-dir.mk,v 1.4 2020/09/01 20:14:34 rillig Exp $
2#
3# Tests for the -m command line option, which adds a directory to the
4# search path for the .include <...> directive.
5#
6# The .../canary.mk special argument starts searching in the current
7# directory and walks towards the file system root, until it finds a
8# directory that contains a file called canary.mk.
9#
10# To set up this scenario, the file step2.mk is created deep in a hierarchy
11# of subdirectories.  Another file called opt-m-step3.mk is created a few
12# steps up in the directory hierarchy, serving as the canary file.
13#
14# Next to the canary file, there is opt-m-step3.mk.  This file is found
15# by mentioning its simple name in an .include directive.  It defines the
16# target "step2" that is needed by "step2.mk".
