That sounds useful.  Please submit a patch against the trunk attached to 
a bug report.

This would certainly be useful functionality.  The link db has changed 
substantially in the current trunk and there is no longer a class named 
Link.  This has been replaced with Inlink and Outlink.  Have a look at 
the trunk and see if what you need isn't already there.

This would also be useful.  Please submit a patch against the trunk.

Any work already done for this? I would love to have multiple values  
and if there is nothing done yet I would love to create such a patch.

Thanks.
