Build the source:

    make


Run the program to show lexer output:

    java -cp bin:lib/java-cup-11b-runtime.jar Main show-lexing input_file


If you have Graphviz installed, you can generate a picture of the parser
output:


    java -cp bin:lib/java-cup-11b-runtime.jar Main show-parsing input_file | dot -Tpng > parser.png


On Microsoft Windows, you will need to write

  "bin;lib/java-cup-11b-runtime.jar"

instead of

  bin:lib/java-cup-11b-runtime.jar

i.e., quote the classpath and use a ; instead of :.
