I see one of my mistakes here.  The person clearly said "you have to
make it with SAP's proprietary build tools/environment."  I didn't
realize you need the build tools/environment to meaningfully view the
code.  Of course, as someone else stated, the build tools/environment
have been open-sourced.

Can someone confirm that the build tools/environment makes the code 
easier to understand?  That would be good, and make it easier for us to
learn from it.
