IIC (Information in Context) is an interactive programming environment meant to be used for profiling and tracing functions, as well as for visualizing information about functions. IIC runs in the Scheme interpreter STk and has both a graphical and a textual user interface. By integrating a profiling environment with a visualization system, IIC gives the programmer the power to dissect the internals of her program. In addition, IIC gives the programmer the power to control what data is gathered through the use of *scope* IIC makes it possible to evaluate the efficiency of functions and to easily identify bottlenecks. IIC can also be useful for debugging. IIC was written by Jen Mankoff (jmankoff@cs.oberlin.edu). Please send her mail if you use it or have questions about it. In order to run IIC, you must load the file "interface.stk", which can be found in the directory named "IIC" which will be created when you untar it.
