+0.60  2009-10-08  - modified \psPrintValue to allow algebraic function mode
+                  - fix bug with algebraic=true for all macros with \psplot
+                    which need postfix code
 0.59  2009-01-23  - add option \psk@xShift for \psPrintValue
 0.58  2008-12-08  - add the ChebyshevT and ChebyshevU (first and second kind)
                     the macros are only wrappers for the PS routines
