| 2 | # EXAMPLE: Rappture optimization |
---|
| 3 | # |
---|
| 4 | # This script shows the core of the Rappture optimization loop. |
---|
| 5 | # It represents a simple skeleton of the much more complicated |
---|
| 6 | # Rappture GUI, but it drives enough of the optimization process |
---|
| 7 | # to drive development and testing. |
---|
| 8 | # |
---|
| 9 | # Run this as: wish simple.tcl ?-tool path/to/tool.xml? |
