 This package consist of functions for computing the Minkowksi sum
 of two polygons in the plane. Namely, given two polygons $P,Q \in
-\reals^2$ it computes $P \oplus Q = \left\{ p + q ~|~ p \in P,
+\mathbb{R}^2$ it computes $P \oplus Q = \left\{ p + q ~|~ p \in P,
 q \in Q \right\}$.
 
 In addition, the package also includes functions for offsetting a
