[pstricks] Redefined math symbol \Pi

[Thorsten Donig]

Hello to all!

Since the last MiKTeX update on June 24th 2006 i have a problem with the 
math symbol for the greek capital Pi. It seems that the pstricks-add 
package from June 18th 2006 redefines the command \Pi in a way, that 
there is given out an error message by the mathpazo package of an 
already defined command. I excluded systematically all other error 
sources. The error occures when including the pstricks-add package 
before the mathpazo package. But i would like to use mathpazo and 
pstricks-add together in the future. When i include pstricks-add after 
mathpazo there is no longer the greek capital but the numerical value 
pi=3.14… and no error message ist given out by the latex compiler. If 
mathpazo is not included, the result is the same. In the psttricks-add 
documentation i found that the value provided by the \Pi command is used 
for axis units when plotting trigonometrical functions. I suggest that 
the command is renamed to \PI or \pstPi (similar to \pstPI2 in pst-math 
package) to avoid collision with other packages and defintions by 
standard class files. Or is there another alternative?

With the best wishes and many greetings from Braunschweig, Germany
