# Interfaces:
# Connection:
# $conn->sockname() returns a connection type specific representation
# string of the local address, or undef if not applicable.
# $conn->peername() returns a connection type specific representation
# string of the remote address, or undef if not applicable.
# $conn->send("string") sends something over the connection.
# $conn->recv() receives a string from the connection, or returns "" if no
# data is available.
# $conn->fds() returns all file descriptors used by the connection, so one
# can use select() on them.
# Channel:
# Usually wraps around a connection and implements a command based
# structure over it. It usually is constructed using new
# ChannelType($connection, someparameters...)
# @cmds = $chan->join_commands(@cmds) joins multiple commands to a single
# command string if the protocol supports it, or does nothing and leaves
# @cmds unchanged if the protocol does not support that usage (this is
# meant to save send() invocations).
# $chan->send($command, $nothrottle) sends a command over the channel. If
# $nothrottle is sent, the command must not be left out even if the channel
# is saturated (for example, because of IRC's flood control mechanism).
# $chan->quote($str) returns a string in a quoted form so it can safely be
# inserted as a substring into a command, or returns $str as is if not
# applicable. It is assumed that the result of the quote method is used
# as part of a quoted string, if the protocol supports that.
# $chan->recv() returns a list of received commands from the channel, or
# the empty list if none are available.
# $conn->fds() returns all file descriptors used by the channel's
# connections, so one can use select() on them.
# Socket connection.
# Represents a connection over a socket.
# Mainly used to wrap a channel around it for, in this case, line based or rcon-like operation.
