   * **BASE_SRC_DIR** This supersedes the older OUTPUT_DIRECTORY setting. Files are generated //relative// to the BASE_SRC_DIR, i.e. taking into account the package naming. If this is unset, BASE_SRC_DIR is assumed to be the directory where the grammar is.   * **BASE_SRC_DIR** This supersedes the older OUTPUT_DIRECTORY setting.

 +  * **DEACTIVATE_TOKENS** This setting allows you to indicate that certain token types are de-activated by default when you instantiate the parser. Something like: ''DEACTIVATE_TOKENS=OPEN_PAREN_CLOSE_PAREN;'' would mean that those two tokens are not //active// by default when you instantiate the parser. Of course, you could use ''ACTIVE_TOKENS(....)'' to activate them when needed in the parse.
   * **ENSURE_FINAL_EOL** With this setting turned on (it is off by default) the generated parser ensures that the input file ends with a newline character. (It tacks one on if it is not present.) This is a nitpicking detail but it is surprisingly difficult to write certain grammars (ones that are very line-oriented) if you cannot be sure that every line (including the last one!) ends with a newline.   * **ENSURE_FINAL_EOL** With this setting turned on (it is off by default) the generated parser ensures that the input file ends with a newline character.
