+Draw and annotate various kinds of timing diagrams in Tikz.
+
+There's no real documentation, read the source and the examples
+(diagrams-examples.tex), and use at your own risks ;-).
+
+The latest version is to be found here:
+
+  https://gitorious.org/tikz-goodies/tikz-goodies
+
+You may want to have a look at tikz-timing too if you want to draw
+some hardware-oriented timing diagrams:
