       ANTLR - ANother Tool for Language Recognition, version 3


       java org.antlr.Tool or antlr3 [args] file.g [ file2.g file3.g ... ]


       ANTLR,  ANother  Tool  for  Language Recognition, (formerly PCCTS) is a language tool that
       provides a  framework  for  constructing  recognizers,  compilers,  and  translators  from
       grammatical descriptions containing C++ or Java actions.

       -o outputDir
              specify output directory where all output generated.

       -fo outputDir
              same as -o but force even files with relative paths to dir.

       -lib dir
              specify location of token files.

              generate file dependencies.

              print out a report about the grammar(s) processed.

       -print print out the grammar without actions.

       -debug generate a parser that emits debugging events.

              generate a parser that computes profiling information.

       -nfa   generate an NFA for each rule.

       -dfa   generate a DFA for each decision point.

       -message-format name
              specify output style for messages.

              generate ANTLR version and other information.

       -make  only build if generated files older than grammar.

              print the version of ANTLR and exit.

       -X     display extended argument list.
