Allowy provides CanCan-like way of checking permission but doesn't enforce a tight DSL giving you more control

Provides a Ruby API to control Vagrant where Vagrant is installed via the Installer package on Mac OS X. Vagrant was historically available as a gem, naturally providing a Ruby API to control Vagrant in other Ruby libraries and applications. However, since version 1.1.0, Vagrant is distributed exclusively using an Installer package. To control Vagrant when it's installed this way, other Ruby libraries and applications typically need to invoke the Vagrant binary, which requires forking a new process and parsing its output using string manipulation.
