 * [The -showtree option pops up a Swing frame that shows
 *  the AST constructed from the parser.]
 *
 * Run 'java Main <directory full of java files>'

 *
 * Version 1.00 December 9, 1997 -- initial release
 * Version 1.01 December 10, 1997
 *		fixed bug in octal def (0..7 not 0..8)
 * Version 1.10 August 1998 (parrt)
 *		added tree construction
 *		fixed definition of WS,comments for mac,pc,unix newlines
 *		added unary plus
 * Version 1.11 (Nov 20, 1998)
 *		Added "shutup" option to turn off last ambig warning.
 *		Fixed inner class def to allow named class defs as statements
 *		synchronized requires compound not simple statement
 *		add [] after builtInType DOT class in primaryExpression
 *		"const" is reserved but not valid..removed from modifiers
 * Version 1.12 (Feb 2, 1999)
 *		Changed LITERAL_xxx to xxx in tree grammar.
 *		Updated java.g to use tokens {...} now for 2.6.0 (new feature).
 *
 * Version 1.13 (Apr 23, 1999)
 *		Didn't have (stat)? for else clause in tree parser.
 *		Didn't gen ASTs for interface extends.  Updated tree parser too.
 *		Updated to 2.6.0.
 * Version 1.14 (Jun 20, 1999)
 *		Allowed final/abstract on local classes.
 *		Removed local interfaces from methods
 *		Put instanceof precedence where it belongs...in relationalExpr
 *			It also had expr not type as arg; fixed it.
 *		Missing ! on SEMI in classBlock
 *		fixed: (expr) + "string" was parsed incorrectly (+ as unary plus).
 *		fixed: didn't like Object[].class in parser or tree parser
 * Version 1.15 (Jun 26, 1999)
 *		Screwed up rule with instanceof in it. :(  Fixed.
 *		Tree parser didn't like (expr).something; fixed.
 *		Allowed multiple inheritance in tree grammar. oops.
 * Version 1.16 (August 22, 1999)
 *		Extending an interface built a wacky tree: had extra EXTENDS.
 *		Tree grammar didn't allow multiple superinterfaces.
 *		Tree grammar didn't allow empty var initializer: {}
 * Version 1.17 (October 12, 1999)
 *		ESC lexer rule allowed 399 max not 377 max.
 *		java.tree.g didn't handle the expression of synchronized
 *		statements.
 * Version 1.18 (August 12, 2001)
 *      	Terence updated to Java 2 Version 1.3 by
 *		observing/combining work of Allan Jacobs and Steve
 *		Messick.  Handles 1.3 src.  Summary:
 *		o  primary didn't include boolean.class kind of thing
 *      	o  constructor calls parsed explicitly now:
 * 		   see explicitConstructorInvocation
 *		o  add strictfp modifier
 *      	o  missing objBlock after new expression in tree grammar
 *		o  merged local class definition alternatives, moved after declaration
 *		o  fixed problem with ClassName.super.field
 *      	o  reordered some alternatives to make things more efficient
 *		o  long and double constants were not differentiated from int/float
 *		o  whitespace rule was inefficient: matched only one char
 *		o  add an examples directory with some nasty 1.3 cases
 *		o  made Main.java use buffered IO and a Reader for Unicode support
 *		o  supports UNICODE?
 *		   Using Unicode charVocabulay makes code file big, but only
 *		   in the bitsets at the end. I need to make ANTLR generate
 *		   unicode bitsets more efficiently.
 * Version 1.19 (April 25, 2002)
 *		Terence added in nice fixes by John Pybus concerning floating
 *		constants and problems with super() calls.  John did a nice
 *		reorg of the primary/postfix expression stuff to read better
 *		and makes f.g.super() parse properly (it was METHOD_CALL not
 *		a SUPER_CTOR_CALL).  Also:
 *
 *		o  "finally" clause was a root...made it a child of "try"
 *		o  Added stuff for asserts too for Java 1.4, but *commented out*
 *		   as it is not backward compatible.
 *
 * Version 1.20 (October 27, 2002)
 *
 *      Terence ended up reorging John Pybus' stuff to
 *      remove some nondeterminisms and some syntactic predicates.
 *      Note that the grammar is stricter now; e.g., this(...) must
 *	be the first statement.
 *
 *      Trinary ?: operator wasn't working as array name:
 *          (isBig ? bigDigits : digits)[i];
 *
 *      Checked parser/tree parser on source for
 *          Resin-2.0.5, jive-2.1.1, jdk 1.3.1, Lucene, antlr 2.7.2a4,
 *	    and the 110k-line jGuru server source.
 *
 * This grammar is in the PUBLIC DOMAIN
