The second part of the project involved expanding the Isthmus tools to automatically generate the interface code required to use propagation patterns in the TclTk environment. The result of this portion of the project is is another tool called isthmus-pp. When this program is used in conjunction with isthmus-cd, all the interface code for both class dictionaries and propagation patterns is automatically created for the programmer. Together the two tools integrate both parts of Demeter.
