(synopsis "Semigroup operations for Haskell")
(description "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.")
