 ##  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.
