#### git diff

The `git diff` tool is very handy, because it shows you a before-and-after comparison of how the current files differ from those in the last commit.
But by default it uses a cryptic line-by-line text format.
Fortunatly there are GUIs for doing this kind of comparison, and one freely available cross-platform tool is Meld.
It can be conveniently installed on Mac OS X via [HomeBrew](http://brew.sh) with the following command:

brew install meld

To set it up with git, follow the instructions in <http://blog.deadlypenguin.com/blog/2011/05/03/using-meld-with-git-diff/>
