gEDA-user: Check for same refdes

[Peter Kaiser <peter@xxxxxxxxxxxx>]

Hello,

is there any possibility to check whether the same refdes attribute is twice 
on the page?

I always run into problems when netlisting and I either forgot to replace the 
R? with R4 or when I copy a block.

The netlister gives no message when R4 appears twice on a page. The netlist is 
wrong.
