         This script, "generate.rb", makes sure the definitions, as stored in
         "definitions.rb", are parsed into the code of the interpreter.
         This scripts is only used by developers, and should not be
         distributed in binary packages.\n
         All changes to the definitions should be made in "definitions.rb".\n
         Use the 'diff' command line option (./generate.rb diff) to see the
         differences.\n
         For more information on the workings see the source of "generate.rb".
