+Installing Apple mDNSResponder:
+
+WARNING: this is NOT Howl's mDNSResponder and it does not come in Debian package called mdnsresponder.
+You can see the difference by checking daemon's name: Apple's one (the correct one) is named 'mdnsd'
+Howl's one is named 'mDNSResponder'.
+
+1) download mDNSResponder
+ - from Apple site (http://www.opensource.apple.com/darwinsource/tarballs/apsl/mDNSResponder-107.tar.gz)
+ - or you can get tarball from: http://helios.et.put.poznan.pl/~jstachow/pub/mDNSResponder-107.tar.gz
+ (for those who don't like registration)
+
+2) compile and install
+ Build system for mDNSResponder is quite weird so here are instructions:
+
+ cd mDNSPosix
+ make os=linux (make without parameters gives list of supported systems)
+ now as root:
+ make os=linux install
+
+ make sure that mdnsd.sh init script is properly installed and will be executed at boot time

+/** @mainpage DNSSD
+
+<p>DNSSD is a library for handling the DNS-based Service Discovery Protocol (DNS-SD),
+the layer of <a href="http://www.zeroconf.org">Zeroconf</a> that allows network
+services, such as printers, to be discovered without any user intervention or
+centralized infrastructure.</p>
+
+Apple's implementation of Zeroconf is
+<a href="http://www.apple.com/macosx/technology/bonjour.html">Bonjour</a>.
+Apple's developer documentation provides lots of information about Bonjour
+in its <a href="http://developer.apple.com/documentation/Cocoa/Conceptual/NetServices/Articles/about.html#//apple_ref/doc/uid/TP40002458-SW1">Bonjour overview</a>.
+
+If you are writing an application that wants to discover services on the network,
+use DNSSD::ServiceBrowser. You can also find available service types using ServiceTypeBrowser.
+
+If you want to announce the availability of a service provided by your application,
+use DNSSD::PublicService.
+
+DNSSD::DomainBrowser allows you to find domains (other than the local one) recommended
+for browsing or publishing to.
+
+Note that DNSSD::ServiceBrowser::isAvailable() provides information about the availability
+of the services provided by this library generally, not just for browsing services.

+Checklist to ensure that zeroconf will work:
+
+1) Install Apple's mdnsd, at least version 85
+2) kdelibs (and kdebase for ksysguard) should be configured and compiled with dns_sd sdk (part
+of mdnsd installation) present - config.h should contain '#define HAVE_DNSSD 1'
+3) check /etc/nsswitch.conf and ensure that there is 'mdns' before 'dns' in
+line starting with 'host:'. It should be something like:
+host: files mdns dns
+4) ensure that mdnsd is being started in initscripts
+5) for testing: use kpf kicker applet to publish a directory, then open 'zeroconf:/'
+URL in konqueror. You should be able to see a local webserver with that published dir.
+
+For more information go here
