Much more complete than the usual login script package. This could actually be of use to a lot of folks, where the usual login script really serves only as an example. It is PHP5 only, unless you modify the class script.
(GENERAL NOTE: Really Guys! There are still a lot of sites out there running PHP4 -- it would be friendly to at least state if a package is PHP5-only or not, tested with PHP4 & 5, or 5 only, etc.)
