- An email feed parser.

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.

that can have new data loaded into it.

    You can also push and pop line-matching predicates onto a stack.  When
the
    current predicate matches the current line, a false EOF response
    (i.e. empty string) is returned instead.  This lets the parser adhere
to a
    simple abstraction -- it parses until EOF closes the current message.
