tikz-cd — Commutative diagrams with TikZ
========================================
The general-purpose drawing package [TikZ][pgf] can be used to typeset
commutative diagrams and other kinds of mathematical pictures,
generating high-quality results. This TikZ library facilitates the
creation of such diagrams by providing a convenient set of macros and
reasonable default settings. It can be used in plain TeX, LaTeX and
ConTeXt. See [the manual][tikz-cd-doc] for further details and many
examples.
