+## 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.
