  14 $! Incorporates Charles Bailey's ideas about bootstrapping system info -
  15 $! myconfig.com is now callable as a "myconfig" target in your maker and
  16 $! may even work if miniperl.exe and config.sh files fail to be made.
  17 $! Thus if:
  18 $!      MMK/DESCRIP=[.VMS]                             !(or MMS or MAKE)
  19 $! does not work then try:
  20 $!      MMK/DESCRIP=[.VMS]/OUTPUT=MYPERLBUILD.PROBLEM  !(or MMS or MAKE)
  21 $! Then discuss the MYPERLBUILD.PROBLEM file with a local expert.
  22 $! If that still does not work then try:
  23 $!      MMK/DESCRIP=[.VMS]/OUT=MYNONFIG.OUT MYCONFIG   !(or MMS or MAKE)
  24 $! send output (MYNONFIG.OUT) to an outside expert and ask politely for help.
