-"""RFC-822 message manipulation class.
-
-XXX This is only a very rough sketch of a full RFC-822 parser;
-in particular the tokenizing of addresses does not adhere to all the
-quoting rules.
-
-Directions for use:
-
-To create a Message object: first open a file, e.g.:
-  fp = open(file, 'r')
-You can use any other legal way of getting an open file object, e.g. use
-sys.stdin or call os.popen().
-Then pass the open file object to the Message() constructor:
-  m = Message(fp)
-
-This class can work with any input object that supports a readline
-method.  If the input object has seek and tell capability, the
-rewindbody method will work; also illegal lines will be pushed back
-onto the input stream.  If the input object lacks seek but has an
-`unread' method that can push back a line of input, Message will use
-that to push back illegal lines.  Thus this class can be used to parse
-messages coming from a buffered stream.
-
-The optional `seekable' argument is provided as a workaround for
-certain stdio libraries in which tell() discards buffered data before
-discovering that the lseek() system call doesn't work.  For maximum
-portability, you should set the seekable argument to zero to prevent
-that initial \code{tell} when passing in an unseekable object such as
-a a file object created from a socket object.  If it is 1 on entry --
-which it is by default -- the tell() method of the open file object is
-called once; if this raises an exception, seekable is reset to 0.  For 
-other nonzero values of seekable, this test is not made.
-
-To get the text of a particular header there are several methods:
-  str = m.getheader(name)
-  str = m.getrawheader(name)
-where name is the name of the header, e.g. 'Subject'.
-The difference is that getheader() strips the leading and trailing
-whitespace, while getrawheader() doesn't.  Both functions retain
-embedded whitespace (including newlines) exactly as they are
-specified in the header, and leave the case of the text unchanged.
-
-For addresses and address lists there are functions
-  realname, mailaddress = m.getaddr(name) and
-  list = m.getaddrlist(name)
-where the latter returns a list of (realname, mailaddr) tuples.
-
-There is also a method
-  time = m.getdate(name)
-which parses a Date-like field and returns a time-compatible tuple,
-i.e. a tuple such as returned by time.localtime() or accepted by
-time.mktime().
-
-See the class definition for lower level access methods.
-
-There are also some utility functions here.
