[snip Richard's python script]

As a firm believer of giving back to the community, here are my
modifications to Richard's script.

	#1) Allows user to specify what type (pc, mac, unix) of lineendings
		they want
	
	#2) Got it to work under MacPython and UnixPython
	
	#3) More detailed output to user
	
	#4) Removed time logging stuff... couldn't get it to work under my
		UnixPython for some reason :-(
	
	#5) Handles .DS_Store files better (by skipping them)
	

Hope this helps someone,
-Ryan Wilcox
