Add the script include-version-info.sh into a new run script build phase of your application target. The build phase 
should be located after the build phase "Copy Bundle Resources".

Follow the instructions here: The Hitchhiker's Guide to Riding a 
Mountain Lion http://j.mp/Qm5UJD, including installing XQuartz.

After installing XQuartz set the correct path to the X11 library to 
install Ruby 1.8.7-p358 with rbenv:

  export CPPFLAGS=-I/opt/X11/include

then let the compiler know where gcc-4.2 is:

Running echo "*.m diff=objc" >> .gitattributes in a git repo tells git to use the obj-c diff algorithm when running git diff. For the most part, this isn't much different from the standard diff algorithm. However, it adds one key benefit.

In a unified git diff, added lines are prefixed with a +, and removed lines are prefixed with a -. Unchanged lines are provided for context, and have no prefix. As added context, though, unified diffs have a @@-prefixed line at the beginning of each hunk. Minimally, the @@ lines specify which lines in the file are being changed. It can also contain a label, if git can determine an appropriate label for that section of code.

By default, the label on a hunk context line is the name of the enclosing C function. That works great for C-ish code, but completely misses Obj-C method signatures. As a result, when diffing Obj-C files, the context label is either empty, or falls back to the last C-ish declaration it could find. This is usually entirely useless.
