Jon Griffin is in the process of making this available in the acs-reference package. He hasn't gotten it bundled up yet.
Also, I tried e-mailing you folks to tell you that your commit of calendar changes was missing some files, but your mail server seems to not always be available. At least 50% of my mail messages to you come back with a "FATAL - couldn't deliver, the server was unavailable for a really long time, we give up" style error messages.
The missing files were .xql files in calendar/www/admin.
