 ## Optional testing dependencies
 * procps and psmisc (if running cts-exec, cts-fencing, or CTS)
 * valgrind (if running CTS valgrind tests)
 * python3-systemd (if using CTS on cluster nodes running systemd)
 * rsync (if running CTS container tests)
 * libvirt-daemon-driver-lxc (if running CTS container tests)
 * libvirt-daemon-lxc (if running CTS container tests)
 * libvirt-login-shell (if running CTS container tests)
 * nmap (if not specifying an IP address base)
 * oprofile (if running CTS profiling tests)
 * dlm (to log DLM debugging info after CTS tests)
 * xmllint (to validate tool output in cts-cli)
 
 ## Simple install
 
     $ make && sudo make install
 
 If GNU make is not your default make, use "gmake" instead.
 
 ## Detailed install
 
 First, browse the build options that are available:
 
     $ ./autogen.sh
     $ ./configure --help
 
 Re-run ./configure with any options you want, then proceed with the simple
 method.
