Having recently acquired an Android device, I started playing around with building a custom ROM image. I downloaded a version of CyanogenMod 7.2 ported for my device and built it successfully.
Since this is a port to my device, I'd be interested in comparing this ported code to the CM7.2 tree to see what kinds of changes went into making the port (since the xml file points to a bunch of different disparate git repos for various components, I'm not sure how I'd go about this). A similar question goes for trying to understand the differences between the CM7.2 port and the stock Android Source.
