Eclipse external tool for Qt .ui to .py with pyuic

I use PyDev in Eclipse with the Qt integration. With an external tool I can create python source in a .py from a qt .ui file. This is the external tool: http://permalink.gmane.org/gmane.comp.python.xy.devel/413 The problem is that the generated python .py file has a name like MyGeneratedFile.ui.py. How can I adapt the external tool to have the extension of the generated file without .ui thus MyGeneratedFile.py ?
