16: As mentioned in the <A HREF="../User/Architecture/">Library Architecture</A>,
17: libwww consists of a small core and a large set of hooks for adding
18: functionality. By itself, the core it not capable of performing any Web related
19: tasks like accessing a HTTP server or parsing a HTML document. All this
20: functionality must be registered by the application. This way, the core of
21: libwww is kept application independent and can be used as the basic building
22: block for any kind of Web application. The Library comes with a large set
23: of default functions, for example for accessing HTTP and FTP servers, parsing
24: <A HREF="http://info.internet.isi.edu:80/in-notes/rfc/files/rfc822.txt">RFC
25: 822</A> headers etc. This module helps the application programmer setting
26: up all this functionality, but it is important to note that none of it is
27: <I>required</I> in order to use the Library.
28: <P>
29: This module is implemented by <A HREF="HTInit.c">HTInit.c</A>, and it is
30: a part of the <A HREF="http://www.w3.org/pub/WWW/Library/">W3C Reference
31: Library</A>. You can also have a look at the other
32: <A HREF="WWWInit.html">Initialization modules</A>.

! 72: <P>
! 73: The core doesn't have any built in MIME parsers, but many of the protocols

92: <P>
93: The <EM>Converters</EM> are used to convert a media type to another media
94: type, or to present it on screen. This is a part of the stream stack algorithm.
95: The Presenters are also used in the stream stack, but are initialized separately.

115: stack, but are initialized separately. The <I>Presenters</I> use the same
