How does the Rappture Toolkit know where to find my tool.xml file?
The rappture command looks for a file named tool.xml in the present working directory. If there is not a file named tool.xml in the present working directory, it will displaying an error stating that it cannot find the tool.xml file.
If you would like the rappture command to use an xml file that is not in the present working directory, or that is not named tool.xml, you can use the -tool option and provide the location and name of the file Rappture should read to load the specification for the graphical user interface.
rappture -tool src/tool.xml rappture -tool mytest.xml
