"""Python package for the generation of PostScript, PDF, and SVG files

PyX is a Python package for the creation of PostScript, PDF, and SVG files. It
combines an abstraction of the PostScript drawing model with a TeX/LaTeX
interface. Complex tasks like 2d and 3d plots in publication-ready quality are
built out of these primitives."""
