John, in general PSTricks has nothing to do with TeX.
It is only an interface to the powerful programming
language PostScript. PStricks uses only TeX when it
puts text anywhere into the given coordinate system
and this only to be sure, that the graphics and the other
text uses the same font. _Every_ known program written
in PostScript, e.g. Runge-Kutta for solving differential
equations, can be run from within TeX via PSTricks.
