This commit proposes a bootstrap flag that can be passed into the contrib subapplication for backwards compatibility if applications disappear from `/usr/bin/`. Backwards compatibility would persist for those that opt into the feature by adding `source $(tilde contrib --bootstrap)` to their ~/.bashrc or added globally with a modification to /etc/bash_profile. Additionally new features would be made available to everyone who uses this command to bootstrap their shell environment as soon as they are approved by a server admin.
