 The configure script provides a shortcut for using valgrind to spot bugs
 related to memory handling. Just add the option
-@code{--toolchain=valgrind-memcheck} to your configure line, and
-reasonable defaults will be set for running FATE under the supervision

 In case you need finer control over how valgrind is invoked, use the
