Travis Swicegood has made a new release of the successor to the PEAR RunTest package for PEAR2 - the new PHPT.
Since this is usable and PEAR2 is still being worked out, I've decided to release this as a standalone package for the time being with the intent of bundling it with Pyrus or including it directly in PEAR2 when PEAR2 is realized.
This provides the majority of the functionality provided by PEAR's pear run-tests command via its own phpt command and it can even provide pear style output.
Examples of its use are included as well as the method to download this latest version (via a PEAR channel, of course) or through the package's web page. Issues found with the software can be posted to the project's Google code page.
