17.4  Development System Support

As seen in the above example, the top level loop indicates floundering by printing a message about delayed goals. The command line toplevel then prompts and offers to print a list of all delayed goals. The Tkeclipse development environment provides better support in the form of the Delayed Goals Viewer, which can be used to look at all delayed goals or a filtered subset of them.

The tracer supports advanced control features via the box-model ports DELAY and RESUME. It also shows goal priorities (if they deviate from the default priority) in angular brackets.
