  11 # This shell script is used by the build system to print out commands that fail
  12 # to execute properly.  It is designed to make the "make -s" command more
  13 # useful.
  14 #
  15 # Note that in the example we are sourcing rather than execing the script.
  16 # Since make already started a shell for us, we might as well use it rather
  17 # than starting a new one.
