Internet Resources
        LAN Services AG (www.lan.ch) 
           for the http://rrdtool.eu.org domain reflector

        Alexander Lucke (lucke@dns-net.de) 
           and DNS:NET Internet Services (www.dns-net.de)
              for http://rrdtool.org

        Matt Levine (matt@deliver3.com)
           for http://rrdtool.com

Further I would like to note, that rrdtool would not exist without
the following free software products:

	Perl by Larry Wall
	gd library by Thomas Boutell
	gifcode from David Koblas
	libpng by Glenn Randers-Pehrson / Andreas Eric Dilger / Guy Eric Schalnat
	cgilib by Martin Schulze
	zlib by Jean-loup Gailly and Mark Adler
	SNMP Perl-Module by Simon Leinen

	and last but not least
	
	Linux by Linus Torvalds	

I would also like to thank the Department of Electrical Engineering
at the Swiss Federal Institute of Technology who allow me to
use their network resources to publish rrdtool ...

During Summer 1999 CAIDA (www.caida.org) has supported me in working full
time on RRDtool ... A big thank you to them as well.
