# 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.

# (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.
# Check to see if the python version is > 3.0 which is currently unsupported
# If so exit with error message
