+ "This package provides semigroups for Haskell. In
+mathematics, a semigroup is an algebraic structure consisting of a set
+together with an associative binary operation. A semigroup generalizes a
+monoid in that there might not exist an identity element. It
+also (originally) generalized a group (a monoid with all inverses) to a type
+where every element did not have to have an inverse, thus the name
+semigroup.")
