A set of build scripts on top of gitian and vagrant for automating gitian builds...

...on any platform using Oracle VirtualBox. A minimum number of host dependencies are required.

The gitian build process produces deterministic builds and living documentation of the build process. However gitian only runs within a Linux host environment, and has proven somewhat tricky to setup and maintain. The purpose of this pull-request is to provide a platform-independent set of scripts for creating a gitian build environment and launching builds for all platforms using Oracle VirtualBox, Vagrant (for recording configurations of VirtualBox; see http://vagrantup.com/), and gitian LXC containers.

See “contrib/vagrant/README.md” for details.
