# SConstruct - build script for the SDL port of fceux
#
# You can adjust the BoolVariables below to include/exclude features at compile-time
#
# You may need to wipe the scons cache ("scons -c") and recompile for some options to take effect.
#
# Use "scons" to compile and "scons install" to install.
