##  This script is the front-end to the build system. It provides a similar
##  interface to standard configure scripts with some extra bits for dealing
##  with toolchains that differ from the standard POSIX interface and
##  for extracting subsets of the source tree. In theory, reusable parts
##  of this script were intended to live in build/make/configure.sh,
##  but in practice, the line is pretty blurry.
##
##  This build system is based in part on the FFmpeg configure script.
