;;; Commentary:
;; This library is meant to provide the glue between modules that want
;; to establish a network connection to a server for protocols such as
;; IMAP, NNTP, SMTP and POP3.
;; The main problem is that there's more than a couple of interfaces
;; towards doing this. You have normal, plain connections, which are
;; no trouble at all, but you also have TLS/SSL connections, and you
;; have STARTTLS. Negotiating this for each protocol can be rather
;; tedious, so this library provides a single entry point, and hides
;; much of the ugliness.
;; Usage example:
;; (open-protocol-stream
;; "*nnimap*" buffer address port
;; :type 'network
;; :capability-command "1 CAPABILITY\r\n"
;; :success " OK "
;; :starttls-function
;; (lambda (capabilities)
;; (if (not (string-match "STARTTLS" capabilities))
;; nil
;; "1 STARTTLS\r\n")))

"Open a network stream to HOST, upgrading to STARTTLS if possible.
The first four parameters have the same meaning as in
`open-network-stream'. The function returns a list where the
first element is the stream, the second element is the greeting
the server replied with after connecting, and the third element
is a string representing the capabilities of the server (if any).
The PARAMETERS is a keyword list that can have the following
values:
:type -- either `network', `tls', `shell' or `starttls'. If
omitted, the default is `network'. `network' will be
opportunistically upgraded to STARTTLS if both the server and
Emacs supports it.
:end-of-command -- a regexp saying what the end of a command is.
This defaults to \"\\n\".
:success -- a regexp saying whether the STARTTLS command was
successful or not. For instance, for NNTP this is \"^3\".
:capability-command -- a string representing the command used to
query server for capabilities. For instance, for IMAP this is
\"1 CAPABILITY\\r\\n\".
:starttls-function -- a function that takes one parameter, which
is the response to the capaibility command. It should return nil
if it turns out that the server doesn't support STARTTLS, or the
command to switch on STARTTLS otherwise."
