| <para>Nulgrind is the simplest possible Valgrind tool. It performs no |
| instrumentation or analysis of a program, just runs it normally. It is |
| mainly of use for Valgrind's developers for debugging and regression |
| testing.</para> |
| |
| <para>Nonetheless you can run programs with Nulgrind. They will run |
| roughly 5 times more slowly than normal, for no useful effect. Note |
| that you need to use the option <option>--tool=none</option> to run |
| Nulgrind (ie. not <option>--tool=nulgrind</option>).</para> |
