# description:
#
#	hostname.pl will add a /HOSTNAME command similar to the one that can
#	be found in BitchX.
#
#	/HOSTNAME will list all IP addresses of your system, and resolve them.
#	/HOSTNAME <index> will switch to the selected IP address.
#
#	The IP addresses are collected by running ifconfig and parsing
#	the output. It has been tested on the following systems:
#
#		FreeBSD 4.4-RELEASE
#		FreeBSD 4.5-RELEASE
#		NetBSD 1.5.2
#		Linux 2.4.16
#		IRIX 6.5
#		OSF/1 4.0
#		SunOS 5.8
#
#	It will probably work on any recent version of the following systems:
#
#		FreeBSD
#		NetBSD
#		OpenBSD
#		Linux
#		IRIX
#		OSF/1 / Tru64
#		SunOS / Solaris
#
#	It may or may not work on other systems / versions, but it will not
#	work on the following pieces of crap:
#
#		M$-DO$ all versions
#		Windoze all versions
#			
#	You'll also need to have the module Socket6.pm installed, the address
#	resolution needs it; on FreeBSD it can be installed easily by typing
#	cd /usr/ports/net/p5-Socket6 && make install
#
# /format's:
#
#	hostname
#
#		$0	index number
#		$1	IP address
#		$2	hostname
#
# new theme abstracts:
#
#	Insert the following in the abstracts section of your theme file:
#
#		index = "[$*]";
#		ip = "%g$*%n";
#		hostname = "{comment $*}";
#
# usage:
#
#	/HOSTNAME [<index>]
#
#	Without arguments, display the list of IP addresses and resolve them.
#
#	With a numerical argument, set the hostname setting to the IP
#	address matching that index in the list.
#
# acknowledgements:
#
#	The following people have sent the ifconfig output of their system:
#	darix, plett, zur
#
# changes:
#
#	2002-07-04	release 1.01
#			* command_bind uses a reference instead of a string
#
#	2002-04-25	release 1.00
#			* increased version number
#
#	2002-02-02	release 0.02
#			* reads ifconfig output one line at a time
#			* excluded too many IP addresses in result: fixed
#			* much '2' today ;)
#
#	2002-02-01	initial release
