  Description     : userspace container engine pecialized for development environments

Vagga is a container engine running solely within userspace, which features
 - Running programs in linux containers (not a full virtualization like Vagrant)
 - Fully userspace containers, no need for elevated privileges like for Docker
 - Runs containerized process as a child of current shell, no attach/detach hell
 - Images are automatically rebuilt and versioned
 - Vagga has tools to manage trees of processes (so you run your redis-python-nginx server with one command)
 - Compatibility with Vagrant-LXC and Docker

With docker there is an outstanding problem of requiring server 
process and elevated priviliges making it a bit tricky to deploy
across e.g. HPC.  Containerization solely within user-space could
provide ultimate solution allowing for e.g. unstable Debian-based 
containers deployed across clusters running stable Debian release.
