The project is kind of split in two. The library and the client. The client
part uses the library, but the library is meant to be designed to allow other
applications to use it.

Library
=======
As described elsewhere, libcurl is meant to get two different "layers" of
interfaces. At the present point only the high-level, the "easy", interface
has been fully implemented and documented. We assume the easy-interface in
this description, the low-level interface will be documented when fully
implemented.
There are plenty of entry points to the library, namely each publicly defined
function that libcurl offers to applications. All of those functions are
rather small and easy-to-follow. All the ones prefixed with 'curl_easy' are

When completed, the curl_easy_cleanup() should be called to free up used
resources.
A quick roundup on internal function sequences (many of these call
protocol-specific function-pointers):
curl_connect - connects to a remote site and does initial connect fluff
This also checks for an existing connection to the requested site and uses
that one if it is possible.
curl_do - starts a transfer
curl_transfer() - transfers data
curl_done - ends a transfer
curl_disconnect - disconnects from a remote site. This is called when the
disconnect is really requested, which doesn't necessarily have to be
exactly after curl_done in case we want to keep the connection open for
a while.

http_chunks.c contains functions that understands HTTP 1.1 chunked transfer
encoding.
An interesting detail with the HTTP(S) request, is the add_buffer() series of
functions we use. They append data to one single buffer, and when the
building is done the entire request is sent off in one single write. This is
done this way to overcome problems with flawed firewalls and lame servers.

To do in a future release:
* Add configure options that disables certain protocols in libcurl to
decrease footprint. '--disable-[protocol]' where protocol is http, ftp,
telnet, ldap, dict or file.
* Extend the test suite to include telnet and https. The telnet could just do
ftp or http operations (for which we have test servers) and the https would
probably work against/with some of the openssl tools.
