    Please add to the Describe method for arcpy the ability to return the version of an ArcToolbox. This will allow a python script to query and reject a toolbox because it was not built for that version of ArcGIS. Whilst the vision of ESRI is to be backwardly compatible and keep legacy code the reality it that this can fail and some method of being able to test a toolbox before loading it is required.
