amscdx – Enhanced commutative diagrams

The original amscd package provides a CD environment that emulates the commutative diagram capabilities of AMS- 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.

This update, 2.2x of 2019-07-02, fixes the dashed-arrows parts placement bug, and adds the package option 'lyx', for use with lyx to prevent conflict with the already loaded amscd. The packages xcolor and graphicx are made required.
