Command line acceptance of binary plugs license?

[Vinod Kutty]

Hi,

I'm trying to build openjdk7-ea-b67, so I downloaded the self-extracting 
binary plugs and tried to extract it.

Unfortunately, it assumes a graphical environment for the license 
agreement and will not proceed further.

Surely there must be a way to interact with the license agreement on the 
command line, similar to how the self-extracting pre-built Sun JDK builds 
do?

I'd appreciate instructions on how to do so.

Thanks,
