10Building and Running Project:
11
12This project outputs to the console. It can be built and executed on QEMU as
13follows:
14
15 make run

19Troubleshooting:
20
21Problems caused by out-dated project information can be addressed by
22issuing one of the following commands then rebuilding the project:
23
24 make clean # discard results of previous builds
25 # but keep existing configuration info
26or
27 make pristine # discard results of previous builds
28 # and restore pre-defined configuration info
