+The original amscd package provides a CD environment that emulates the commutative diagram capabilities of AMS-TEX version 2.x. This means that only simple rectangular diagrams are supported, with no diagonal arrows or more exotic features.
+
+This enhancement package amscdx implements double (”fat”) and dashed arrows also in both directions (left-right and up-down), and color attributes for arrows and their annotations. The restriction to rectangular geometry remains. This nevertheless allows the drawing of a much broader class of "commutative-diagram-like" diagrams.
