I have written many Python scripts using arcpy in ArcGIS 10, and so far my only means of debugging is restricted to printing messages to the geoprocessing results window using arcpy.AddMessage(). Are there any other options out there, such as setting break points? This would save a lot of time and frustration.




**EDIT**

Jason's method works great. If you have a bug in your toolbox, such as validation, your IDE probably won't be able to pinpoint the problem because toolboxes are encoded. At least WING wasn't able to pinpoint it.
