Title: Formula for The Silver Searcher (ag), a faster ack

The Silver Searcher, also known as ag, is a smarter, faster version of ack, written in C.

In order to compile this on 10.6.x, you will have to use --devel --HEAD for now.
The current release of ag uses getline and strndup functions, which are only in 10.7 and above;
I've updated the program with implementations of those functions, but they have yet to make it into a release.
