arcpy - Intersecting two shapefiles from different folders based on their name using scripting in ArcGIS Desktop?

How can i script for intersecting the two shape files from two different folders based on their names?

i have two folders which contains the shape files with same name i want to intersect the shapefiles based on their name, scripting should pick the files based on their name from two different folders and output file should store in another folder.

I'm using ArcGIS Desktop 9.3 and arcgisscripting (that preceded ArcPy).
