/**
* 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>
