+@subsection Expression input @uref{derivative.cpp, (source)}
+
+Interactively input expression and compute its derivative with respect
+to the ``x'' variable.

@chapter Monte Carlo Integration
@section Example showing compile_ex @uref{compile1.cpp, (source)}
Demonstrates the use of link_ex. Program has to be called more than once to see the effect.
+@chapter Lanczos Approximation
+
+The program lanczos.cpp calculates coefficients for use in the Lanczos
+approximation of the gamma function. The Lanczos approximation is used by
+the function inside GiNaC that approximates the gamma function numerically.
+See the comments in the source file for more information.
