Demo: Creating a Full LAPACK Documentation

All the tools introduced here can be combined for creating a cool Fortran documentation tool. The lapackdoc script is such a bundle:

For each LAPACK source file a cross referenced and syntax highlighted HTML listing gets created.
If a LAPACK source file contains embedded documentation it gets extracted.
The documentation gets enhanced by call and caller graph.

Note: Creating the call and caller graphs for a large software project is pretty time consuming. Actually a half the time gets used up by Graphviz dot command.
