Thank you, Peter. Don't hesitate to state the obvious. I have done exactly as you describe and have a simple test case defined and running. Now, it's a matter of working through several examples to become familiar with the automated testing API.
I take it that -init.tcl and -procs.tcl are handled the same as the same named files in the tcl/ directory? Where -init.tcl files are executed on startup and -procs.tcl files are simply loaded as libraries.
