  *	@brief Represents a connected IRC Session.
  *
  *	IRCClientSession represents a single connection to an IRC server. On initialising
- *  the object, and setting the delegate, server, port, password, nickname, username and realname
- *	properties, you call the connect: and run: methods to connect to the IRC server
- *	and start a new thread.
+ *  the object, and setting the delegate, server, port, and password (if required)
+ *	properties, and setting the nickname, username and realname using the
+ *	setNickname:username:realname: method, you call the connect: and run: methods 
+ *	to connect to the IRC server and start a new thread.
  *
- *	This thread then sends messages back to the main runloop to the IRC server delegate,
- *	or to the IRCClientChannel delegate as required.
+ *	This thread then sends messages to the IRC server delegate,

 ADDING IRCCLIENT TO YOUR APPLICATION

 6. Import IRCClient’s API into your code using “#import <IRCClient/IRCClient.h>”

+
+NOTE on strings:
+
+IRCClient stores and passes all strings (messages, nicks, channel names, mode strings, channel topics, etc.) as NSData objects, which contain null-terminated C strings. Values passed to framework methods (such as the IRC commands) should also be in this format[1]. This means that IRCClient is encoding-agnostic[2]; it is up to you to pass it properly encoded C-string representations of your text strings, and it is also up to you to select an appropriate encoding for display or other handling of received strings, as necessary. The 'encoding' property of IRCClientSession and IRCClientChannel may be useful in this regard (i.e. for the convenience associating a server's or channel's preferred encoding with the relevant server or channel object), although note that this property is almost entirely epiphenomenal[3].
+
+[1] Although note that if you pass unterminated strings instead, IRCClient will add the null termination for you - but there is a slight performance penalty for this, so be sure to null-terminate the contents of your NSData objects, for optimal performance.
+
+[2] Of course, IRCClient does not support UTF-16 nor any other non-8-bit encoding (since the byte representations of such encodings may contain nulls, and therefore cannot be used as C strings), but the IRC protocol does not support such encodings either.
+
+[3] The 'encoding' property of IRCClientSession does have one effect: it controls the encoding used by replies to CTCP TIME requests.
