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