 * Configures the manager using command-line arguments.
 * The arguments are checked in their command line sequence.
 * If an argument begins with {@link Command#COMMAND_PREFIX},
 * its part that follows it is treated as a (long) command's name.
 * If an argument begins with {@link Command#SWITCH_PREFIX},
 * the following character(s) are treated as a switch.
 * The name or switch extracted this way, prepended with
 * a bean name prefix for a {@link #BEAN_NAME_PREFIX_COMMAND command}
 * or a {@link #BEAN_NAME_PREFIX_SWITCH switch}, becomes the name
 * of a bean to look up in the framework's
 * {@link #MAIN_BEAN_CONFIG_FILE configuration file(s)}.
 * The bean that handles a command must extend the
 * {@link Command} class. Once a suitable bean is found,
 * it is called to act upon the command or switch and process
 * any additional arguments associated with it. 
 * If no bean can be found or the argument is not prefixed
 * properly, it is considered unclaimed. You may configure a
 * special subclass of {@link Command} to process such arguments
 * by placing a bean named {@link #BEAN_NAME_DEFAULT_HANDLER} on
 * the configuration. If there is no such bean configured, or when
 * any {@link Command} bean throws an exception while processing
 * a command, a command line error is reported and the application
 * quits./*w w  w .  j a  va 2  s.  c o  m*/
