+############################
+# Y: [SUGGESTED]. These lines define connection classes. Connection
+# classes allow you to fine-tune your client and server connections.
+# Since the fields have different meanings for server and client classes
+# you shouldn't mix them, and if you have lots of server connections (if 
+# you do have lots of servers you shouldn't be reading this file :-) each 
+# set of servers (defined arbitrarily by you) should have its own class. 
+# If you have clients coming in from lots of different sites, you may want 
+# to seperate them out into classes. For instance, you may want to put 
+# local users in one class, with remote users in another class. You may also
+# want to put limits on some client classes (one client only for indials
+# for example).  In any larger network you definitely want to do this.
+#
+# For SERVER CLASSES, the fields are: 
+# Y:<Class>:<Ping Frequency>:<Connect freq>:<Max Links>:<SendQ>::
+#    1       2                3              4           5      67
+#   1 class number
+#   2 ping frequency (in seconds)
+#   3 connect frequency (in seconds)
+#   4 maximum number of automatically initiated links in this class
+#   5 sendq
+#   6 unused for server classes
+#   7 unused for server classes
+#
+# Sendq have the format <x>.<y>, where x defines sendq whereas y defines
+# burst sendq. It is useful to have for example 1MB normal sendq and 20MB
+# of burst sendq, which allows for quicker broken link detection.
+#
+# The class numbers are not arbitrary.  In auto-connecting servers -- that is,
+# servers that you have a port number (e.g. 6667) on the end of the C: line 
+# (see below) the higher the number the higher the priority in auto-connecting.
+#
+# Note that it is a good idea to have ping frequency the same at both ends
+# of the link.
+#
+# This is a normal (uncompressed) server connection (normal as of January, 2005)
+# Y:<Class>:<Ping Frequencys>:<Connect freq>:<Max Links>:<SendQ>::
+Y:2:90:300:1:20000000::

+# For CLIENT CLASSES, the fields are:
+# Y:<Class>:<Ping Frequency>::<Max Links>:<SendQ>:<Local Limit>:<Global Limit>:
+#    1       2               3 4           5       6             7
+#   1 class number
+#   2 ping frequency (in seconds)
+#   3 unused for client classes
+#   4 maximum number of links in this class (per I line)
+#   5 sendQ for each client
+#   6 maximum number of links from this [user@]host on the server
+#   7 maximum number of links from this [user@]host on the net
+#
+# Local and global limits have the format <x>.<y> where x defines the maximum
+# number of clients from the same host (IP) whereas y defines the maximum 
+# number of clients from the same user@host (IP) allowed to connect.  the
+# latter uses the identd replies to identify a user, falling back to an
+# @host limit if no identd runs on the client and fails for identds generating 
+# dynamical answers.
+#
+# Note that any unset values default to zero which means 'unlimited', except
+# for limits, where default is 1.1

+# O: [OPTIONAL]. These lines define operator access. You do not need to

+# using some other nick at that moment '/oper Nickname' will do also.
