   6 #   scons debug=1 dri=0 machine=x86
   7 #
   8 # to set configuration variables. Or you can write those options to a file
   9 # named config.py:
  10 #
  11 #   # config.py
  12 #   debug=1
  13 #   dri=0
  14 #   machine='x86'
  15 #
  16 # Invoke
  17 #
  18 #   scons -h
  19 #
  20 # to get the full list of options. See scons manpage for more info.
