+/**
+ *  The class `WordExp` provides regular word expressions.
+ *
+ *  Users have to instantiate type member `_regexpT <;: RegExp`
+ *  (from class `Base`) and a type member `_labelT <;: Label`.
+ *
+ *  Here is a short example:
+ *  {{{
+ *  import scala.util.regexp._
+ *  import scala.util.automata._
+ *  object MyLang extends WordExp {
+ *    type _regexpT = RegExp
+ *    type _labelT = MyChar
+ *
+ *    case class MyChar(c:Char) extends Label
+ *  }
+ *  import MyLang._
+ *  // (a* | b)*
+ *  val rex = Star(Alt(Star(Letter(MyChar('a'))),Letter(MyChar('b'))))
+ *  object MyBerriSethi extends WordBerrySethi {
+ *    override val lang = MyLang
+ *  }
+ *  val nfa = MyBerriSethi.automatonFrom(Sequ(rex), 1)
+ *  }}}
+ *
