/**
 * Generates a correct application directory based on several rules. If
 * the <tt>MIDP_HOME</tt> environment variable is set, its value is used
 * unmodified. Otherwise, this function will search for the <tt>appdb</tt>
 * directory in the following order:
 * <ul>
 * <li>current directory (if the MIDP executable is in the <tt>PATH</tt>
 *     environment variable and the current directory is the right place)
 * <li>the parent directory of the midp executable
 * <li>the grandparent directory of the midp executable
 * </ul>
 * <p>
 * If <tt>cmd</tt> does not contain a directory (i.e. just the text
 * <tt>midp</tt>), the search starts from the current directory. Otherwise,
 * the search starts from the directory specified in <tt>cmd</tt> (i.e.
 * start in the directory <tt>bin</tt> if <tt>cmd</tt> is <tt>bin/midp</tt>).
 * <p>
 * <b>NOTE:</b> This is only applicable for development platforms.
 *
 * @param cmd A 'C' string containing the command used to start MIDP.
 * @return A 'C' string the found MIDP home directory, otherwise
 *         <tt>NULL</tt>, this will be a static buffer, so that it safe
 *       to call this function before midpInitialize, don't free it
