This reminds me of fucking_shell_scripts[1] but this looks a lot simpler and less angry. I love the idea of truly having no dependencies, since I thought f_s_s was actually written in Bash but turns out to be written in Ruby. BashBooster on the other hand just relies on Bash (no gems, no Ruby) and looks easy to set up. I will definitely be trying it out.

EDIT: BashBooster says it's developed to be used with Vagrant, whereas f_s_s is stand-alone. So it doesn't quite require nothing.
