This script converts your CenterICQ contacts (AIM/ICQ) to BitlBee's contacts.
The use of this script is on you own risk. You agree by using this script. :-)

SYNTAX: `basename $0` <protoname> [<add_proto_tag>]

	protoname     - Choose the protocol you want to get your contacts from
			by using "aim" or "icq" here.

	add_proto_tag - This is optional and adds a suffix to each nickname.
			For an AIM contact it will look like this: geno|aim
			For an ICQ contact it will be |icq , WOW! :-D
			To enable this option use "on". 

NOTE:
	After the conversion of one protocol is done you will find a file
	called bitlbee_[protoname] in ~/.centericq . Append the content of
	this file to /var/lib/bitlbee/[username].nicks .

	[username] is your username you use to talk to the BitlBee Server.
	You will have to be root to edit this file!

CREDITS:
	This script was written by geno (geno@xenyon.com).
	I hope it will help you to make the switch to BitlBee a bit easier. :-)
