+       005    RPL_BOUNCE
+              "Try server <server name>, port <port number>"
+
+         - Sent by the server to a user to suggest an alternative
+           server.  This is often used when the connection is
+           refused because the server is already full.
+
+       302    RPL_USERHOST
+              ":*1<reply> *( " " <reply> )"
+
+         - Reply format used by USERHOST to list replies to
+           the query list.  The reply string is composed as
+           follows:
+
+           reply = nickname [ "*" ] "=" ( "+" / "-" ) hostname
+
+           The '*' indicates whether the client has registered
+           as an Operator.  The '-' or '+' characters represent
+           whether the client has set an AWAY message or not
+           respectively.
+
+       303    RPL_ISON
+              ":*1<nick> *( " " <nick> )"

+              ":You have been marked as being away"
+
+         - These replies are used with the AWAY command (if
+           allowed).  RPL_AWAY is sent to any client sending a
+           PRIVMSG to a client which is away.  RPL_AWAY is only
+           sent by the server to which the client is connected.
+           Replies RPL_UNAWAY and RPL_NOWAWAY are sent when the
+           client removes and sets an AWAY message.

+              "<nick> :*( ( "@" / "+" ) <channel> " " )"
+
+         - Replies 311 - 313, 317 - 319 are all replies
+           generated in response to a WHOIS message.  Given that
+           there are enough parameters present, the answering
+           server MUST either formulate a reply out of the above
+           numerics (if the query nick is found) or return an
+           error reply.  The '*' in RPL_WHOISUSER is there as
+           the literal character and not as a wild card.  For
+           each reply set, only RPL_WHOISCHANNELS may appear
+           more than once (for long lists of channel names).
+           The '@' and '+' characters next to the channel name
+           indicate whether a client is a channel operator or
+           has been granted permission to speak on a moderated
+           channel.  The RPL_ENDOFWHOIS reply is used to mark
+           the end of processing a WHOIS message.

+       369    RPL_ENDOFWHOWAS
+              "<nick> :End of WHOWAS"
+
+         - When replying to a WHOWAS message, a server MUST use
+           the replies RPL_WHOWASUSER, RPL_WHOISSERVER or
+           ERR_WASNOSUCHNICK for each nickname in the presented
+           list.  At the end of all reply batches, there MUST
+           be RPL_ENDOFWHOWAS (even if there was only one reply
+           and it was an error).
+
+       321    RPL_LISTSTART

+              ":End of LIST"
+
+         - Replies RPL_LIST, RPL_LISTEND mark the actual replies
+           with data and end of the server's response to a LIST
+           command.  If there are no channels available to return,
+           only the end reply MUST be sent.

+       332    RPL_TOPIC
+              "<channel> :<topic>"
+
+         - When sending a TOPIC message to determine the
+           channel topic, one of two replies is sent.  If
+           the topic is set, RPL_TOPIC is sent back else
+           RPL_NOTOPIC.
+
+       341    RPL_INVITING
+              "<channel> <nick>"
+
+         - Returned by the server to indicate that the
+           attempted INVITE message was successful and is
+           being passed onto the end client.

+       347    RPL_ENDOFINVITELIST
+              "<channel> :End of channel invite list"
+
+         - When listing the 'invitations masks' for a given channel,
+           a server is required to send the list back using the
+           RPL_INVITELIST and RPL_ENDOFINVITELIST messages.  A
+           separate RPL_INVITELIST is sent for each active mask.
+           After the masks have been listed (or if none present) a
+           RPL_ENDOFINVITELIST MUST be sent.
+
+       348    RPL_EXCEPTLIST
+              "<channel> <exceptionmask>"

+
+         - When listing the 'exception masks' for a given channel,
+           a server is required to send the list back using the

+
+         - Reply by the server showing its version details.
+           The <version> is the version of the software being
+           used (including any patchlevel revisions) and the
+           <debuglevel> is used to indicate if the server is
+           running in "debug mode".
+
+           The "comments" field may contain any comments about
+           the version or further version details.
+
+       352    RPL_WHOREPLY
+              "<channel> <user> <host> <server> <nick>
+              ( "H" / "G" > ["*"] [ ( "@" / "+" ) ]
+              :<hopcount> <real name>"
+
+       315    RPL_ENDOFWHO
+              "<name> :End of WHO list"
+
+         - The RPL_WHOREPLY and RPL_ENDOFWHO pair are used
+           to answer a WHO message.  The RPL_WHOREPLY is only
+           sent if there is an appropriate match to the WHO
+           query.  If there is a list of parameters supplied
+           with a WHO message, a RPL_ENDOFWHO MUST be sent
+           after processing each list item with <name> being
+           the item.
+
+       353    RPL_NAMREPLY
+              "( "=" / "*" / "@" ) <channel>
+               :[ "@" / "+" ] <nick> *( " " [ "@" / "+" ] <nick> )
+         - "@" is used for secret channels, "*" for private
+           channels, and "=" for others (public channels).
+
+       366    RPL_ENDOFNAMES
+              "<channel> :End of NAMES list"
+
+         - To reply to a NAMES message, a reply pair consisting
+           of RPL_NAMREPLY and RPL_ENDOFNAMES is sent by the
+           server back to the client.  If there is no channel
+           found as in the query, then only RPL_ENDOFNAMES is
+           returned.  The exception to this is when a NAMES
+           message is sent with no parameters and all visible
+           channels and contents are sent back in a series of
+           RPL_NAMEREPLY messages with a RPL_ENDOFNAMES to mark
+           the end.
+
+       364    RPL_LINKS
+              "<mask> <server> :<hopcount> <server info>"
+       365    RPL_ENDOFLINKS
+              "<mask> :End of LINKS list"
+
+         - In replying to the LINKS message, a server MUST send

+              "<channel> <banmask>"
+       368    RPL_ENDOFBANLIST
+              "<channel> :End of channel ban list"
+
+         - When listing the active 'bans' for a given channel,
+           a server is required to send the list back using the
+           RPL_BANLIST and RPL_ENDOFBANLIST messages.  A separate
+           RPL_BANLIST is sent for each active banmask.  After the
+           banmasks have been listed (or if none present) a
+           RPL_ENDOFBANLIST MUST be sent.
+
+       371    RPL_INFO
+              ":<string>"
+       374    RPL_ENDOFINFO
+              ":End of INFO list"
+
+         - A server responding to an INFO message is required to
+           send all its 'info' in a series of RPL_INFO messages
+           with a RPL_ENDOFINFO reply to indicate the end of the
+           replies.
+
+       375    RPL_MOTDSTART
+              ":- <server> Message of the day - "
+       372    RPL_MOTD
+              ":- <text>"
+       376    RPL_ENDOFMOTD
+              ":End of MOTD command"
+
+         - When responding to the MOTD message and the MOTD file
+           is found, the file is displayed line by line, with
+           each line no longer than 80 characters, using
+           RPL_MOTD format replies.  These MUST be surrounded
+           by a RPL_MOTDSTART (before the RPL_MOTDs) and an
+           RPL_ENDOFMOTD (after).
+
+       381    RPL_YOUREOPER
+              ":You are now an IRC operator"
+
+         - RPL_YOUREOPER is sent back to a client which has
+           just successfully issued an OPER message and gained
+           operator status.
+
+       382    RPL_REHASHING
+              "<config file> :Rehashing"
+
+         - If the REHASH option is used and an operator sends
+           a REHASH message, an RPL_REHASHING is sent back to
+           the operator.
+
+       383    RPL_YOURESERVICE
+              "You are service <servicename>"
+
+         - Sent by the server to a service upon successful
+           registration.
+
+       391    RPL_TIME
+              "<server> :<string showing server's local time>"
+
+         - When replying to the TIME message, a server MUST send
+           the reply using the RPL_TIME format above.  The string
+           showing the time need only contain the correct day and
+           time there.  There is no further requirement for the
+           time string.
+
+       392    RPL_USERSSTART
+              ":UserID   Terminal  Host"
+       393    RPL_USERS
+              ":<username> <ttyline> <hostname>"

+              ":End of users"
+       395    RPL_NOUSERS
+              ":Nobody logged in"
+
+         - If the USERS message is handled by a server, the
+           replies RPL_USERSTART, RPL_USERS, RPL_ENDOFUSERS and
+           RPL_NOUSERS are used.  RPL_USERSSTART MUST be sent
+           first, following by either a sequence of RPL_USERS
+           or a single RPL_NOUSER.  Following this is
+           RPL_ENDOFUSERS.

+              "<server name> <version & debug level> :End of TRACE"
+
+         - The RPL_TRACE* are all returned by the server in
+           response to the TRACE message.  How many are
+           returned is dependent on the TRACE message and
+           whether it was sent by an operator or not.  There
+           is no predefined order for which occurs first.
+           Replies RPL_TRACEUNKNOWN, RPL_TRACECONNECTING and
+           RPL_TRACEHANDSHAKE are all used for connections
+           which have not been fully established and are either
+           unknown, still attempting to connect or in the
+           process of completing the 'server handshake'.
+           RPL_TRACELINK is sent by any server which handles
+           a TRACE message and has to pass it on to another
+           server.  The list of RPL_TRACELINKs sent in
+           response to a TRACE command traversing the IRC
+           network should reflect the actual connectivity of
+           the servers themselves along that path.
+
+           RPL_TRACENEWTYPE is to be used for any connection
