# For example, invoke scons as 
#
14
#   scons debug=1 dri=0 machine=x86
15 16 17 18 19 20 21
#
# to set configuration variables. Or you can write those options to a file

#   # config.py
#   debug=1
#   dri=0
22
#   machine='x86'
23 24 25 26 27 28 29 30
# 
# Invoke
#
#   scons -h
#
# to get the full list of options. See scons manpage for more info.
