## configure
##
## 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.
