   7 # This shell script is used by the build system to print out commands that fail
   8 # to execute properly.  It is designed to make the "make -s" command more
   9 # useful.
  10 #
  11 # Note that in the example we are sourcing rather than execing the script.
  12 # Since make already started a shell for us, we might as well use it rather
  13 # than starting a new one.
