simple XML build files and extensible PHP "task" classes make it an easy-to-use and highly flexible build framework. 
Features include file transformations (e.g. token replacement, XSLT transformation, Smarty template transformations, 
etc.), file system operations, interactive build support, SQL execution, and much more.');
