      <title>FIFO pipe</title>
      
      <para>
        You can remote control WeeChat, by sending commands or text to a
        FIFO pipe (you have to enable option "irc_fifo_pipe", it is disabled
        by default).
      </para>
      
      <para>
        The FIFO pipe is located in "<literal>~/.weechat/</literal>" and is
        called "weechat_fifo_xxxxx" (where xxxxx is the process ID (PID) of
        running WeeChat). So if many WeeChat are running, you have many FIFO
        pipes, one for each session.
      </para>
      
      <para>
        The syntax for the FIFO pipe commands/text is:
        <screen>server,channel *text or command here</screen>
        where server and channel are optional, but if channel is here, server
        should be too.
      </para>

              send two commands to unload/reload Perl scripts (you have to

        You can write a script to send command to all running WeeChat at same
        time, for example:
<screen>
#!/bin/sh
if [ $# -eq 1 ]; then
    for fifo in $(/bin/ls ~/.weechat/weechat_fifo_* 2>/dev/null); do
        echo -e "$1" >$fifo
    done
fi
</screen>
        If the script is called "auto_weechat_command", you can run it with:
        <screen><prompt>$ </prompt><userinput>./auto_weechat_command "freenode,#weechat *hello"</userinput></screen>

      <para>
        A plugin is a C program which can call WeeChat functions defined in
        an interface.
      </para>
      
      <para>
        This C program does not need WeeChat sources to compile and can be
        dynamically loaded into WeeChat with command
        <command>/plugin</command>.
      </para>
      
      <para>
        The plugin has to be a dynamic library, for dynamic loading by
        operating system.
        Under GNU/Linux, the file has ".so" extension, ".dll" under
        Windows.

        The plugin has to include "weechat-plugin.h" file (available in
        WeeChat source code).
        This file defines structures and types used to communicate with
        WeeChat.

        The plugin must have some variables and functions (mandatory,
