+% 3.0
+% Many changes in this release.
+% - Compatibility with pdflatex using auto-pst-pdf.
+% - New gpicture environment and new gusepicture command.

+% \drawarc[linecolor=black](0,10,20,0,45)
+% \drawarc[arcPie=y,linecolor=blue](0,10,20,-50,-15)

+% \drawsnake[linecolor=red,snakeh=.8,snakew=.8](0,7.5)(0,0.5)
+%
+% 2.9:
+% - added the parameters loopwidth and loopheight to be able to set
+% independently the width and height of loops. loopdiam still exists and set
+% both loopwidth and loopheight to the same value.
+% - added the example "ex-gastex-pdflatex.tex" which contains instructions how
+% to use gastex directly with pdflatex using the package auto-pst-pdf
