In a new post to his blog Stuart Herbert has introduced phix, a packaging tools that can be used to manage and install different components in a framework-agnostic sort of way.

phix is a small command-line tool for PHP applications. I created it to fix (pun intended) the problem of how to easily automate the tasks involved in creating and (especially) maintaining components. These tasks aren't built into phix; they are commands that ship with the phix distribution. You can create your own commands to run inside phix too, and it's easy to do so

The phix tool (easily installed from PEAR) lets you either use built-in commands or custom ones to manage libraries with a few different kinds of commands - current status, initialize a library, upgrade a library and manage the full web application. As of the time of this post, the current version is phix-0.10.4.
