Travis Swicegood is teasing us with some output from a script in his latest blog post:
So my free time of late (what there is of it) has been spent on a project that's getting really close to v0.1 release. In other words, its first functional release. If you've ever run a test using the PEAR installer or know what a .phpt file looks like, you might be able to guess what I've been up.
Keep an eye on his blog for more information on his "secret project".
