示例1: _sortPkgDepsRev
/**
* Compare two package's package.xml, and sort
* so that dependencies are uninstalled last
*
* This is a crude compare, real dependency checking is done on uninstall.
* The only purpose this serves is to make the command-line
* order-independent (you can list a dependency first, and
* uninstallation occurs in the order required)
* @access private
