title: How to add executable to path on gem install with rubygems?
body: <p>I've created a program that I want to bundle into a gem that will add the executable located in the <code>bin</code> directory to the path. I'm wondering if there is something inside the gemspec that I have to set to make this happen, or if it's something else. I want to be able to use <code>gem install gem_name</code> and it will add the executable to the path. How do I do this?</p>
