* <li>a multiple directory option {@link Runtime#INPUT_DIRECTORY} for the file search path,
* <li>a directory option {@link Runtime#OUTPUT_DIRECTORY} for the output directory,
* <li>a word option {@link Runtime#INPUT_ENCODING} for the character encoding when reading
* files,
* <li>a word option {@link Runtime#OUTPUT_ENCODING} for the character encoding when writing
* files,
* <li>
* <li>a boolean option <code>optionDiagnostics</code> for printing tool diagnostics,
* <li>a boolean option <code>optionPerformance</code> for collecting performance statistics,
* <li>a boolean option <code>optionMeasureParser</code> for measuring parser performance only.
* <li>a boolean option <code>optionMeasureProcessing</code> for measuring processing
* performance only.
* <li>a boolean option <code>optionGC</code> for performing GC,
