+difficult to learn since the syntax of @code{\\psplot} and
+@code{\\parametricplot} requires some PostScript knowledge.  The infix-RPN and
+@code{pst-infixplot} styles simplify the usage of @code{pst-plot} for the
+beginner, providing macro commands that convert natural mathematical
+expressions to PostScript syntax.")
