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