6.2.1 Building an interface program

Examples of interface programs are given in the directory examples/interface-tutorial and examples/interface-tour.

The interface programs use a set of C or Fortran routines which should be used to build the interface program. The simplest way to learn how to build an interface program is to customize the previous skeletons files and to look at the examples provided in this directory. Note that a unique interface program can be used to interface an arbitrary (but less that $ 99$) number of functions.
