Thanks, this was very helpful, but even the most recent version seemd to lack a walkcycle with the character walking away from the camera (ie. upscreen). I couldn't use the forward walkcycle because then the knees and elbows bent in a disconcerting direction. So... I hacked on the Forward.xml file one evenring to create a passable walkcycle for this.
I can't attach it to this post, and its pretty long (so I didn't want to inline it in this post), It can be found at http://mysite.verizon.net/~patbobw/Back.xml
Sorry, I'm not very web-tech savvy, so browsers won't follow the link and display anything meaningful. You can wget the file from the link, or open it in a browser and view the page source to see the XML, then cut-n-paste that into a file. The one thing you can't do is open the link in a browser and save it to a file -- the browser seems to mangle the file because its trying to interpret it somehow.
Hope this helps.
SSH: feel free to bundle this with the generator if you want -- a back walkkcycle is the last significant bit of functionality that's missing. Mine's not perfect, but its pretty close.
