[ic] Please specify the VendURL directive

[David Etheredge]

The VendURL is specified in catalog.cfg ( refers back to variable.txt in 
products ) but I keep getting this error.

__________
Configuring catalog topart...topart config error: Please specify the VendURL 
directive in the configuration file 'catalog.cfg'
topart: config error. Skipping.
failed.

Am I supposed to directly configure this one in the catalog.cfg ?
