Xcode feature request: generate "schemes"

The "xcodebuild archive" command requires a "scheme"; it does not work with 
just a target and a configuration.  I'm currently using a "workspace" 
(constructed by hand in the gui) to store my scheme settings, but it would be 
better if the schemes could be defined in the gyp-generated project (perhaps 
specified as a list of target-configuration pairs?  I'm not sure what else is 
useful to specify in schemes).

Of course if I'm missing something and it's possible to do this without 
schemes, please let me know.  (My real goal is to script the process of 
building and packaging the app for testflight and the app store)
