This makes it possible to simply wrap a command inside a container. This makes
it easier to use a container as an unified build environment.
Examples:
~/workspace/docker
$ docker run -v `pwd`:`pwd` -w `pwd` -i -t ubuntu ls
AUTHORS Makefile archive.go changes.go docker
[...]
docker run -v `pwd`:`pwd` -w `pwd` -i -t ubuntu pwd
/home/marco/workspace/docker
