Dipping a Toe in the XUL

Lately I've spent a lot of time tinkering with XUL. Actually creating the markup is pretty simple, certainly no more difficult than HTML or XSL. The real dificulty lies in creating all of the different files for distribution. After toying with it for a little while, I realized that I don't really want all of the XUL structural components (at least for now). What I really want is "privileged" JavaScript - JS without the usual security restrictions. By creating a .manifest file and placing it in the appropriate location, I found I could use privileged JS with ordinary XHTML files. Sweet!
