      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".
