+These tests can be safely run on any Linux system, even those where the kernel
+does not support seccomp-bpf (seccomp mode 2).  However, be warned that the
+test run can take a while to run and produces a lot of output.
+
+The generated seccomp-bpf filters can be tested on a live system using the
+"live" tests; they can be executed using the following commands:
+
+       # make check-build
+       # (cd tests; ./regression -T live)
+
+These tests will fail if the running Linux Kernel does not provide the
+necessary support.
