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. +""" +# Cleanup and extensions by Eric S.
