-.TH II 1 ic\-VERSION
-.SH NAME
-ic \- irc it or irc improved
-.SH DESCRIPTION
-.B ic
-is a minimalistic FIFO and filesystem based IRC client.
-It creates an irc directory tree with server, channel and
-nick name directories.
-In every directory a FIFO file (in) and normal file (out)
-is placed. This will be for example ~/irc/irc.freenode.net/.
-The in file is used to communicate with the servers and the out
-files includes the server messages. For every channel and every nick
-name there will be new in and out files.
-The basic idea of this is to be able to communicate with an IRC
-server with basic command line tools.
-For example if you will join a channel just do echo "/j #channel" > in
-and ic creates a new channel directory with in and out file.
-.SH SYNOPSIS
-.B ic
-.RB < \-s
-.IR servername >
-.RB [ \-p
-.IR port ]
-.RB [ \-k
-.IR "environment variable" ]
-.RB [ \-i
-.IR prefix ]
-.RB [ \-n
-.IR nickname ]
-.RB [ \-f
-.IR realname ]
-.RB < \-u
-.IR sockname >
-.SH OPTIONS
-.TP
-.BI \-s " servername"
-server to connect to, for example: irc.freenode.net
-.TP
-.BI \-u " sockname"
-connect to a UNIX domain socket instead of directly to a server.
-.TP
-.BI \-p " port"
-lets you override the default port (6667)
-.TP
-.BI \-k " environment variable"
-lets you specify an environment variable that contains your IRC password, e.g. IIPASS="foobar" ic -k IIPASS.
-This is done in order to prevent other users from eavesdropping the server password via the process list.
-.TP
-.BI \-i " prefix"
-lets you override the default irc path (~/irc)
-.TP
-.BI \-n " nickname"
-lets you override the default nick ($USER)
-.TP
-.BI \-f " realname"
-lets you specify your real name associated with your nick
-.SH DIRECTORIES
-.TP
-.B ~/irc
-In this directory the irc tree will be created. In this directory you
-will find a directory for your server (default: irc.freenode.net) in
-which the FIFO and the output file will be stored.
-If you join a channel a new directory with the name of the channel
-will be created in the ~/irc/$servername/ directory.
-.SH COMMANDS
-.TP
-.BI /a " [<message>]"
-mark yourself as away
-.TP
-.BI /j " #channel/nickname [<message>]"
-join a channel or open private conversation with user
-.TP
-.BI /l " [reason]"
-leave a channel or query
-.TP
-.BI /n " nick"
-change the nick name
-.TP
-.BI /q " [reason]"
-quit ic
-.TP
-.BI /t " topic"
-set the topic of a channel
-.SH RAW COMMANDS
-.LP
-Everything which is not a command will be posted into the channel or to the server.
-So if you need /who just write /WHO as described in RFC#1459 to the server in FIFO.
-.SH SSL PROTOCOL SUPPORT
-.LP
-For TLS/SSL protocol support you can connect to a local tunnel, for example with stunnel or socat.
-.SH CONTACT
-.LP
-Subscribe to the mailinglist and write to dev (at) suckless (dot) org for suggestions, fixes, etc.
-.SH AUTHORS
-ic engineers, see LICENSE file
-.SH SEE ALSO
-.BR echo (1),
-.BR tail (1)
-.SH BUGS
-Please report them!
