 v1 of this repository used a totally different architecture and had different goals to the current version.

 This repo, `php-build` shouldn't change very regularly, but when it does, the entire build pipeline of dependent repositories will need refreshing. This is done by adding the version of `php-build` to the end of build package names. When a new release is made that affects php-build functionality, the variable at the top of `php-build.bash` can be updated to invalidate any caches.
