# This is the cut-and-paste logic so that a self-contained script can
# interoperate correctly with different SCons versions and installation
# locations for the engine. If you modify anything in this section, you
# should also change other scripts that use this same header.

# Strip the script directory from sys.path() so on case-insensitive
# (WIN32) systems Python doesn't think that the "scons" script is the
# "SCons" package. Replace it with our own library directories
# (version-specific first, in case they installed by hand there,
# followed by generic) so we pick up the right version of the build
# engine modules if they're in either directory.
