00406     Created:        21/6/93
00407     Purpose:                The Tool type reflects the latest Tool specification. Do NOT subclass from
00408                 Tool, but use the latest Tool revision (e.g. Tool_v42). The Tool type should
00409                 only be used by the Kernel and OIL layers, never by tools themselves.
