I wanted a recursive directory brute forcer that was fast, and had certain features (like header blacklisting, and recursion). It didn't exist, so I started writing this. In reality, I'll probably merge a lot of the functionality into github.com/swarley7/gograbber since that solves a similar problem and has cool features that I don't want to implement (phantomjs, ugh). For now, it will do. Important releases will also be tagged and uploaded.
