[Fwd: Patch to display parent hosts in extinfo.cgi]

[matthias eble]

Hi Andreas, hi Ton,

so I'll try the proof of concept and re-submit this patch as I think
this is quite neat (it still applies to latest version).

BTW: What you think about introducing a counterpart of the parents
directive to be able to define child hosts also.
This would make it easily possible to display hosts' children in the
cgis which is a good thing also IMO.
But on the other hand NDO/Merlin/whatever's data models would also be
affected, wouldn't they?.

I know the CGIs will probably not last so long any more, but maybe you
could give us a peek on your plans for their future. 

Thanks in advance and good luck in your new roles. 
Matthias
