- * Return the name to display for the given component.
- * <p>
- * This name is built from the name of the component selected in the Components view.
- * The rules to build the name are:
- * <ol>
- * <li>If the component name does not start with "org.eclipse" then the part name is just
- * "<b>component name</b>"</li>
- * <li>Otherwise, remove "org.eclipse." form the component name and count
- * the tokens separated by a dot ('.')
- * <ul>
- * <li>If there's only one remaining token, then the part name is "<b>Platform/</b>"
- * followed by:
- * <ul>
- * <li>"<b><i>TOKEN</i></b>" if token is less than 3 characters,</li>
- * <li>"<b><i>Token</i></b>" otherwise</li>
- * </ul>
- * </li>
- * <li>Otherwise then the part name is "<b><i>FIRST_TOKEN</i></b>" followed by:
- * <ul>
- * <li>for each followed additional token:
- * <ul>
- * <li>"<b><i>TOKEN</i></b>" if token is less than 3 characters,</li>
- * <li>"<b><i>Token</i></b>" otherwise</li>
- * </ul>
- * </li>
- * </ul>
- * </li>
- * </ul>
- * </ol>

- * <li>org.eclipse.team -> "Platform/Team"</li>
