-      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.  PGF works with plain (pdf-)TeX, (pdf-)LaTeX, and
-      ConTeXt.  Unlike pstricks , it can produce either PostScript or
-      PDF output.
