I wanted to use Robo, but I've got an environment that only has PHP 5.3.
The first thing I said was "well, this is craptastic." And like that, a framework was born.
CrapTasktic: A Task Runner that's compatible with a terribly old version of PHP (i.e. 5.3).
If you have PHP 5.4+ please use Robo.
In fact, this library is a port of Robo with some changes to make it fit our environment better.
