[cups.general] Where is the "mdns" backend?

[Till Kamppeter]

Hi,

probably many of you have seend my earlier posting announcing my "dnssd" 
backend, a simple Perl script which discovers network printers via 
DNS-SD/Zeroconf. It simply runs the "avahi-browse" command and then 
processes the output.

Now I have seen the following STR (feature request):

http://www.cups.org/str.php?L2433

The reporter says it is valid for all systems and he talks about an 
"mdns" backend which seems to do the same thing as my "dnssd" backend. 
So I searched the repositories of CUPS 1.3.x and 1.4.x for this backend 
and I could not find it. Where do I find it? Or is it a proprietary 
add-on which Apple adds to CUPS for Mac OS X?

Should I perhaps rename my backend to "mdns" so that there is an "mdns" 
for all systems? Or could the CUPS "mdns" backend be made available for 
all systems?

    Till

P. S.: Who did not see my announcement, here is the link to the backend 
again:

http://www.openprinting.org/download/printing/dnssd

Download it, put it into /usr/lib/cups/backend/, make it executable, and 
now more printers get discovered than by "snmp" or you get more info 
about your printers.
