    Title:      Tracing functions
    Package:    Standard Function Library (SFL)

    Synopsis:   Provides functions for a programmer who needs to insert
                long-term tracing code in software.  The tracing code is
                activated and disactivated at run-time, for instance when
                problems are suspected.
