###### Examples:

The following is an example tweaklet:

       <extension point="org.eclipse.ui.internalTweaklets">
          <tweaklet
             id="org.eclipse.ui.internal.tweaklets.ConcreteXYZTweaklet"
             name="XYZ Tweaklet"
             description="Short description of the tweak"
             definition="org.eclipse.ui.internal.tweaklets.AbstractXYZTweaklet"
             implementation="org.eclipse.ui.internal.tweaklets.ConcreteXYZTweaklet"
             icon="icons/XYZ.png"/>
       </extension>

###### API Information:

Typically, although not required, the value of the `definition` attribute is the fully qualified name of an abstract class or an interface defined by the workbench, and the value of the `implementation` attribute is the fully qualified name of a non-abstract class provided by the extending plug-in.

###### Supplied Implementation:

Tweaklet implementations can be found in the Eclipse Platform incubator.
