/**
 *
 * <p>Input type to select targets to install </p>
 * If the osSpecific flag is set the OS of the current system will
 * be appended to the name of the target actually by ant run so that different
 * Targets can be run according to the target platform.
 * This feature goes against the principles of
 * building cross platform installers, but is provided so that common installer
 * tasks such as creating icons and shortcuts can be run on Windows for
 * all those useless users who can't run a command script ;)
 * <br>
 * Currently there are two modes strict and not strict (lax).</p>
 * <p>Strict target will return the target name plus the exact String in the
 * System Property "os.name" this means you will have to provide targets for
 * every possible OS version. See
 * <a href="http://lopica.sourceforge.net/os.html">this page</a> for a list of possible values
 * There are a great many but you may not want to consider some of the options.</p>
 * <p>Lax target will return one of the following strings only
 * <ul>
 * <li>"[target-name]-linux" - Linux </li>
 * <li>"[target-name]-mac" - Mac OS and Mac OS X</li>
 * <li>"[target-name]-sun" - SunOS and Solaris</li>
 * <li>"[target-name]-win" - Windows *</li>
 * <li>"[target-name]-other" - any thing else</li>
 * </ul></p> so you only have to create 5 ant targets to support all the cases.
