These files are defined to be used in both host OS and c756-exer tools container configuratios.
After modifying any of these files, run xfer.shto transfer the
updated files into the profiles subdirectory of the c756-exer repo.
Then commit the updated files to c756-exer as well.
Note that xfer.sh does more than simply copy the files: It also
modifies their settings to match the different environment in c756-exer.
