I am looking for a parser library for RFC 822 headers.  The interface
could be something like this:

	1) First call some function that parses the headers from a
text stream (fil, buffer, whatever), and stores it in some internal
data structure. 

	2) After this, you can call funtions to enumerate and retrieve
what headers were present.  The headers are available both in "raw"
form (exactly as in the text stream), and in some pre-digested form
with comments stripped, multiple recipients in a linked list, dates
converted to time_t (or perhaps struct tm), etc.

Not wanting to re-invent the wheel, is such a beast perhaps already
(freely) available?  Thanks for any pointers. Reply by both posting
(to the benefit of others, and I'm probably too busy to make a
summary), and by mail (I might forget what newsgroups I posted this
question to :-), please.
