#
# Sample multilib configuration which the user can either add in local.conf
# or specific in an configuration file like this, then require it.
#
# This configuration specifies an x86 64 bit machine as the main machine
# type and then adds a multilib in the "lib32" directory where those
# libraries are compiled with the "x86" tune.
