"""Python package for the generation of PostScript and PDF files
PyX is a Python package for the creation of PostScript and PDF 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.
