An extensive collection of macros for generating PostScript
that is usable with most TeX macro formats, including Plain
TeX, LaTeX, AMS-TeX, and AMS-LaTeX. Included are macros for
colour, graphics, pie charts, rotation, trees and overlays. It
has many special features, including a wide variety of graphics
(picture drawing) macros, with a flexible interface and with
colour support. There are macros for colouring or shading the
cells of tables. The package pstricks-add contains bug-fixes
and additions for pstricks (among other things). PSTricks uses
PostScript \special commands, which are not supported by
PDF(La)TeX. This limitation may be overcome by using either the
pst-pdf or the pdftricks package, to generate a PDF inclusion
from a PSTricks diagram.
