# to do two separate builds, one for each arch, and then do something like:
#  lipo -create core_i386.dylib core_x86_64.dylib -output core_ub.dylib
#
# If building on 10.5/10.6, it's possible that you could actually build a UB
# for Intel/PowerPC, but please don't. ;) Consider this a proof of concept
# for now just to test a few cores.

#CORE BUILD SUMMARY
#==================

# BUILD_REVISIONS
# ===============
#
# libretro-super can save a revision string (e.g., the git sha hash) for any
# core it has compiled.  If this feature is enabled, it will check if the
# revison string has changed before it compiles the core.  This can speed up
# the build process for end-users and buildbots, and it also results in nightly
# build directories being smaller.  It is not enabled by default because it
# cannot know about uncommitted changes in a working directory.

# Set this to enable the feature
#SKIP_UNCHANGED=1

# Set this if you don't like the default
