+description         Vega visualization grammar — declarative interactive visualizations
+
+long_description    Vega is a visualization grammar, a declarative language for \
+                    creating, saving, and sharing interactive visualization designs. \
+                    With Vega, you can describe the visual appearance and interactive \
+                    behavior of a visualization in a JSON format, and generate \
+                    web-based views using Canvas or SVG. This port installs the Vega \
+                    command-line utilities (vg2png, vg2svg, vg2pdf) and the Vega \
+                    JavaScript library.

+# setup.py installs the dot2tex binary via two mechanisms:
