See the INSTALL document for info on configuring and compiling
ircd-hybrid.

IMPORTANT. if you are used to using "ONE" in the password field
of I lines to limit clients to one per ip, hybrid-5 no longer does it
that way. It now does it the same way CSr does it. The limit is set
by the normally unused (for clients) confreq field in the corresponding
Y line.

TRANSLATION: You *MUST* fix your I and Y lines to be hybrid-5
compatible before running hybrid-5.

LOTS OF THINGS HAVE CHANGED IN CONFIG.H.  PLEASE READ THROUGH IT.

NEW DEBUGGING MODE: if you run ircd with the -s flag, it will send
errors that are normally syslogged to stderr.  This is very useful
if you don't have syslogging set up and ircd won't run.
