Questions about ERP

Hi

I just came across the the GNUe project while searching for Open Source 
ERP software, and have a few questions.

Is the ERP still in the planning stages only? Is there any code at all 
that has started to be written?

Can somebody explain a little more about the developer tools... it seems 
to me that they could be used 'as-is' to establish an ERP (or any other 
type of database driven system) quite easily.

Thanks
