$url (parse-spec) function
The URL word given by parse-spec is returned, where the URL portion must begin with http://, https:// or ftp:// delimited by a blank space. If the parse-spec value does not return a URL, the match specification is not matched. This function is especially useful in a nested specification. (See further section.)
