------------------------------------------
This is a function for deleting information on a tool that has been registered in the robot controller in advance.

**Example**

.. code-block:: cpp

   #include "DRFLEx.h"
   using namespace DRAFramework;

   int main() {
       CDRFLEx drfl;

       float fCog[3]     = {10.f, 10.f, 10.f};
       float fInertia[6] = {0.f, 0.f, 0.f, 0.f, 0.f, 0.f};

       // (1) Register and activate a new tool
       drfl.add_tool("tool#1", 5.3f, fCog, fInertia);
       drfl.set_tool("tool#1");

       // (2) Delete the registered tool
       drfl.del_tool("tool#1");
   }

This example registers a new tool ("tool#1"),  
activates it, and then deletes its registration data from the controller memory.
