Ruby will, be default, print out an ugly stack trace when you ctrl-c (that is, send a SIGINT) to a process. This is pretty much never the behavior I want.
I got tired of copy+pasting the same few lines into every one of my scripts to make this behavior better, so this is instead a gem I can require.
Installation
[$]> gem install nice-sigint
Usage
require 'nice-sigint'
