Sample Buildfile

The following buildfile shows you how to add the adaptive partitioning module to procnto. It also includes commands that create partitions, start a program in the partition, and set the security level.

Note: In a real buildfile, you can't use a backslash (\) to break a long line into shorter pieces, but we've done that here, just to make the buildfile easier to read.

    # in setuid/setgid executables.
