/**
 * The Graphical MIDlet suite manager.
 * <p>
 * Starts with a selector that provides a list of MIDlet suites and
 * a set of commands to perform. It displays the MIDlet names for a suite
 * under the MIDlet suite name, except if there is only one suite then
 * instead of display the suite name, MIDlet-1 name and icon are used.
 * <p>
 * The commands are:</p>
 * <ul>
 * <li><b>Install</b>: Let the user install a suite from a list suites
 * obtained using an HTML URL given by the user. This list is derived by
 * extracting the links with hrefs that are in quotes and end with ".jad" from
 * the HTML page. An href in an extracted link is assumed to be an absolute
 * URL for a MIDP application descriptor.</li>
 * <li><b>Launch</b>: Launch the suite the user selected.
 * <li><b>Remove</b>: Remove the suite (with confirmation) the user selected.
 * </li>
 * <li><b>Update</b>: Update the suite the user selected.</li>
 * <li><b>Info</b>: Show the user general information of the selected suite.
 * <li><b>Settings</b>: Let the user change the manager's settings.
 * </ul>
