EMail Tree in Python

Hi,

while working on gpgit.py, I needed a function to show me how the content of an email was structured. I came up with this:

def print_email_mime_tree(email_obj):
	tree = [email_obj]
	deep = 0
	while not len(tree) == 0: 
		pay = tree.pop()
		if pay == "":
			deep -= 1
		else:
			print("	" * deep + "|")
			print("	" * deep + "|" + pay.get_content_type())
			if pay.is_multipart():
				deep += 1
				tree.append("")
				tree.extend(reversed(pay.get_payload()))

It will print the structure in the form of:

I hope it comes in as handy for you as it was for me!
