A version of VRfreewill is included in Hal, however, it's not the same as another (more useful) plugin of the same name.
There is no updated manual as far as I have found but several of the members here are very handy like that.
In the File Sharing area of the forum, there is a page with the most currently updated plugins. For the most part, none of the user plugins have been incorporated into Hal.
