# revision control systems. You can tweak this delay using --max-drift=SECONDS
# where SECONDS is some number of seconds. Decreasing SECONDS can improve build
# speed by eliminating superfluous MD5 checksum calculations. Instead of
# specifying this on the command line each run, you can set this option inside
# your SConstruct or SConscript file using "SetOption('max_drift', SECONDS)".
