+
+The feed parser implements an interface for incrementally parsing an email
+message, line by line.  This has advantages for certain applications, such as
+those reading email messages off a socket.
+
+FeedParser.feed() is the primary interface for pushing new data into the
+parser.  It returns when there's nothing more it can do with the available
+data.  When you have no more data to push into the parser, call .close().
+This completes the parsing and returns the root message object.
+
+The other advantage of this parser is that it will never raise a parsing
+exception.  Instead, when it finds something unexpected, it adds a 'defect' to
+the current message.  Defects are just instances that live on the message
+object's .defects attribute.

+This module handles the content transfer encoding method defined in RFC 2045
+to encode US ASCII-like 8-bit data called `quoted-printable'.  It is used to
+safely encode text that is in a character set similar to the 7-bit US ASCII
+character set, but that includes some 8-bit characters that are normally not
+allowed in email bodies or headers.
+
+Quoted-printable is very space-inefficient for encoding binary files; use the
+email.base64mime module for that instead.
+
+This module provides an interface to encode and decode both headers and bodies
+with quoted-printable encoding.
+
+RFC 2045 defines a method for including character set information in an
+`encoded-word' in a header.  This method is commonly used for 8-bit real names
+in To:/From:/Cc: etc. fields, as well as Subject: lines.
+
+This module does not do the line wrapping or end-of-line character
+conversion necessary for proper internationalized headers; it only
+does dumb encoding and decoding.  To deal with the various line
+wrapping issues, use the email.header module.

+
+Unlike the test test_nested-multiples-with-internal-boundary, this
+piece of text not only contains the outer boundary tags 
+------- =_aaaaaaaaaa1 
+and 
+------- =_aaaaaaaaaa0 
+but puts them at the start of a line! And, to be even nastier, it
+even includes a couple of end tags, such as this one:
+
+------- =_aaaaaaaaaa1--
+
+and this one, which is from a multipart we haven't even seen yet!
+
+------- =_aaaaaaaaaa4--
+
+This will, I'm sure, cause much breakage of MIME parsers. But, as 
+far as I can tell, it's perfectly legal. I have not yet ever seen
+a case of this in the wild, but I've seen *similar* things.
