| ## 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. |
