   3 ##  configure
   4 ##
   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.
  11 ##
  12 ##  This build system is based in part on the FFmpeg configure script.
