+shortdesc PSTricks package for plotting mathematical functions.
+longdesc pst-func is a package built for use with PSTricks. It provides
+longdesc macros for plotting various mathematical functions. Polynomials
+longdesc and their derivatives $f(x)=an*x^n+an-1*x^(n-1)+...+a0$ defined by
+longdesc the coefficients a0 a1 a2 ... and the derivative order; the
+longdesc Fourier sum f(x) = a0/2+a1cos(omega x)+...+b1sin(omega x)+...
+longdesc defined by the coefficients a0 a1 a2 ... b1 b2 b3 ...; the Bessel
+longdesc function defined by its order; and the Gauss function defined by
