Custom file role

I'm trying to use PEAR for deploying an entire web application as opposed to just libraries. My scenario is simple...everything in my tarball needs to go into a web tree. I've created a Web role (Web.php) extending the Custom role and I've got it packaged up and installing fine to the PEAR/Installer/Role directory. Problem is when I try to deploy my app using the Web role I'm getting: PEAR_PackageFileManager2 Error: Invalid file role passed to addRole, must be one of "data, doc, php, script, test", was passed "web" I'm not 100% how all this stuff stitches together but I noticed in the PEAR/Installer/Role directory each role PHP script has a corresponding .xml file. Is that my problem? I'm guessing I'm missing a simple step here. --Tony
