FujiNetChat is inspired by irssi. However, since it runs on a tiny
8-bit platform, it can't do all the things irssi does. Here's a
partial list of the user-visible differences.

- Can't connect to multiple servers.
- No /server command (you have to run the config tool to change
  servers; this may change in future).
- Most preferences can't be changed from within the client (have to
  use the config tool). Exceptions: nick and alert type.
- No SASL auth support.
- Obviously, no scripting.
- No DCC.
- No logging.
- No color.
- You only get 7 screens (windows).
- Can't disable the server screen.
- No auto-rejoin on when kicked.
- No auto-reconnect when disconnected (you have to press a key to
  reconnect). This will change.
- There's a [private] screen for all PMs which don't have a /query.
- /query <nick> <message> doesn't work (yet). It creates a query but
  doesn't (yet) send the initial message.
- Getting PMed doesn't create a screen (use Start+Q to do that).
- Closing a screen doesn't /part the channel (it "moves" to [server]).
- No command history (up-arrow) or cutbuffer (^Y).
- No local nick list, which means tab-completion is limited, and
  that we can't keep track of who's opped or voiced, so no @ or
  + in front of nicks.
