How do you produce one static library for both release/debug on the iPhone?

I would like to release a static library similar to what PayPal did (https://www.x.com/community/ppx/xspaces/mobile/mep) for the iPhone. They were successful in incorporating both the release/debug version of their static libraries into one single *.a file. I have found solutions to combine simu开发者_StackOverflowlator/device static libraries but not combining release/debug libraries without causing a collision on platform. (http://blog.costan.us/2009/12/fat-iphone-static-libraries-device-and.html) Does anyone know how to produce a library that combines the release and debug versions of a static library?
