Summary description:  Enhanced commutative diagrams

Announcement text:
----------------------------------------------------------------------

 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 implements double (“fat”), dashed, and
 bidirectional arrows  (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.
