Re: [buckminster-dev] Still fuzzy on generators/artifacts

[Thomas Hallgren <thomas@xxxxxxx>]

Hi Todd,
I don't think the generator concept is widely used at present and I haven't got around to write any 
demo sample for it just yet. We added it to support some use-cases in Buckminster that we since then 
moved away from (we moved from Axis with and interfaces generated from WSDL to using JSON).

I'm more then happy to help though but in order to do that, you must tell me some more about what 
specific problems that you are facing.

Regards,
Thomas Hallgren
