December 2011 - Guarding Your Projects - Using Guard

Guard is a command line tool that easily handles events on file modifications. The primary use for guard is to automatically run tests based on changes to source files, but because of its modular nature, it can do much more. We’ll quickly cover typical setup and use, as well as alternative uses, and maybe even write our own guard gem for fun.
