PGF is a macro package for creating graphics.  It is platform- and 
format-independent and works together with the most important TeX backend 
drivers, including pdftex and dvips. It comes with a user-friedly syntax 
layer called TikZ.

Its usage is similar to pstricks and the standard picture environment.  
Unlike pstricks, it can produce either PostScript or PDF output, and works 
with plain (pdf-)TeX, (pdf-)LaTeX, and ConTeXt.

Release notes:
This new version of pgf/TikZ contains new features and fixes a number of
bugs. A notable new feature is the new math library due to Mark Wibrow, which
allows you to use fancy mathematical expressions directly inside TikZ. This
release also includes a matrix library, which simplifies alignments. There
are now commands that allow you to extract pictures into separate files more
asily. Some users will also enjoy the new calendar support. Finallly, if you
have always been looking for an easy way to create a triangular shape, have a
look at Mark's regular polygon shape.

Although this version should already be perfectly usable and reasonably
bug-free, it is still a beta-version. Release 1.20 will be the next stable
version. I will release it within a few weeks, once I got feedback on this
