# this script is used to rebuild the Android emulator from sources
# in the current directory. It also contains logic to speed up the
# rebuild if it detects that you're using the Android build system
#
# in this case, it will use prebuilt binaries for the compiler,
# the audio library and the SDL library. You can disable this
# by using the --no-prebuilt-libs and --cc=<compiler> options
#
#
# here's the list of environment variables you can define before
# calling this script to control it (besides options):
