[Python-checkins] CVS: python/dist/src/Lib/email Parser.py,1.4,1.5

[Barry Warsaw]

Update of /cvsroot/python/python/dist/src/Lib/email
In directory usw-pr-cvs1:/tmp/cvs-serv27728

Modified Files:
	Parser.py 
Log Message:
HeaderParser: A new subclass of Parser which only parses the message
headers.  It does not parse the body of the message, instead simply
assigning it as a string to the container's payload.  This can be much
faster when you're only interested in a message's header.
