public class Boot
extends Utils

command line for the parser generator bootstrapped with oops3 (only first letter of each option is significant). The options are to facilitate experiments with the algorithms; they must be used in proper order and they do not interlock on errors.

-build new name file [builder-class [scanner-class]]	use a parser to build a new tree
-Build new name file [builder-class [scanner-class]]	... and show trace
-dump name	dump a tree
-Dump name	... and include lookahead if any
-epilog name	output epilog from a parser
-generate [path]name.style [options]	generate frontend, shorthand for -Input boot pj2/style.ser -build name boot [path]name.style pj2.StyleBuilder -prolog name -jay name -main [options] -scanner name -tree name -epilog name
-Generate [path]name.style [options]	generate frontend, do not store null for an empty alternative
-input name file	input a serialized tree
-Input name resource	... from a resource, not a file
-jay name [flags]	output input for jay to create a parser; flags toggle error handling, see Gen
-Jay name [flags]	output input for jay to create a parser and do not store null for an empty alternative; flags toggle error handling, see Gen
-main [animate [0|1|2|3]|tree [builder]]	output main program [animate or build tree [with builder]]
-prolog name	output prolog from a parser
-scanner name[.lex]	generate scanner from parser or file with JLex
