dotjs is a Google Chrome extension that executes JavaScript files in
~/.js based
on their filename.
If you navigate tohttp://www.google.com/, dotjs will execute
~/.js/google.com.js.
This makes it super easy to spruce up your favorite pages using JavaScript.
Bonus: files in ~/.js have jQuery 1.6 loaded, regardless of whether the site
you're hacking uses jQuery.
Double bonus: `~/.js/default.js` is loaded on every request, meaning you can
stick plugins or helper functions in it.
GreaseMonkey user scripts are great, but you need to publish them somewhere
and re-publish after making modifications. With dotjs, just add or edit
files in ~/.js.
