* {@link ezcConsoleTable} through {@link ezcConsoleInput::getHelpTable()}
* are can generate a printable help text through {@link
* ezcConsoleInput::getHelpText()}.
*
* The parameter $long defines if the long or short help text of the
* options should be used in the second cell of the returned array. The
* $optionsFilter parameter is used to restrict the generated help to a certain
* sub-set of options. It consists of an array of short or long names of
