+and implements the @code{stdlib} @code{Set} interface for them.  It also
+offers an alternate paradigm of @code{String} processing which grants much
+better performance than @code{Regexp} and @code{String} methods from the
+@code{stdlib} where applicable.  Many parts can be used independently, e.g.:

+@item @code{CharacterSet::Parser}
+@item @code{CharacterSet::Writer}
+@item @code{RangeCompressor}
