## 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.
