The "meme" chat protocol
Elliott Hird, December 2007

= Message format ===============================================================
<message> = <tag>\t<command>[\t<args>]\n

<tag> is a base-10 number.
<command> is one of the valid commands (described below).

<args> = <key>: <value>[\t<args>]

<key> is one of the valid argument names for the command.
<value> is any UTF-8 string -- to escape tabs, use '\t' in the message, and to
escape backslashes, use '\.'.

= Example message ==============================================================
(Note: replace 8 spaces with a tab.)

1        hello        client: netcat        user: ehird

= Server responses =============================================================
<response> = <tag>\t<status>[\t<args>]\n

<tag> and <args> are the same as above, <status> is either "ok" or "fail".

The arguments given are command-specific.
