The ccontrol program takes over the roles of the
compiler and linker, and reads a configuration
file to decide what to do before invoking them.
This is particularly useful for centralized
control over commands and options, such as
enabling distcc(1) and ccache(1).
virtbench is a set of benchmarks for
virtualization environments / hypervisors. It is
designed to be easy to run and easy to extend. The
main audience will be people developing hypervisors.
