How do I register a service with Bonjour?

I am trying to start to use Bonjour. Here I found a manual how to register a service with Bonjour. The following is written there:

The network services architecture in Bonjour includes an easy-to-use mechanism for publishing, discovering, and using IP-based services.

Well let's see how to register a service. In the very beginning it is written:

To publish a service, an application or device must register the service with a Multicast DNS responder

But how?!?! First of all I do not know what is the Multicast DNS responder. Second, it is not written how do I do it. Where and what should I type? Should I use command line? Should I use some programming languages? What exactly should I type...

Is there an easy way to start to use Bonjour? Well, it was emphasized several times how easy it should be to use it. But I cannot start to use it for several day.

So, can anybody, pleas, help me with that?

• This may be a good place to start :

  Roman : Using this link I have downloaded the Bonjour. But I still do not know how to to use it (for example to register a service or to discover available services). On the page you gave me there is a FAQ. Among the questions there is "What should I pass in for the "name" parameter when registering a service?". Bat I have no ideas how to register a service, how to find this "name" parameter or where to write it. I think there is a gap between the very beginning and practical usage of the Bonjour.

• From the command line on OSX you can use mDNS or its alias dns-sd. I seem to recall that one or other of those also exists builtin to Vista and later.

  To do it in a program, you need to go ask again at stackoverflow.com

  From Alnitak

• you could user something like

  mDNS -R myssh _ssh._tcp local 222
  

  which would register ssh on a nonstandard port (222).

  http://www.manpagez.com/man/1/mDNS/ shows the list of available parameters and further pointers to other documentation.
