I don't think it's documented via perldoc (at least I don't remember having seen any for it); that's why I guess it was designed for internal use. I heard someone mention it once, but I don't know how you'd discover it was there except by "using the source, Luke" =)

It sure beats having to import URI::Escape as well as CGI =)
