Provides a generic function optval, which can be used to
conveniently implement fallback values for optional arguments
to subprograms
(Specification )
If x is an optional parameter of a
subprogram, then the expression optval(x, default) inside that
subprogram evaluates to x if it is present, otherwise default.
It is an error to call optval with a single actual argument.

Solid arrows point from a submodule to the (sub)module which it is
descended from. Dashed arrows point from a module or program unit to
modules which it uses. Where possible, edges connecting nodes are given different colours to make them easier to distinguish in large graphs.
