-
-============================================================================
-
-This file contains the build instructions for the ANTLR toolset as
-of version 3.1.3 and beyond.
-
-The ANTLR toolset must be built using the Maven build system as
-this build system updates the version numbers and controls the
-whole build process. However, if you just want the latest build
-and do not care to learn anything about Maven, then visit the 'target'
-directories (for jars) under the depot mirror root here:
-
-   http://antlr.org/depot
-
-If you are looking for the latest released version of ANTLR, then
-visit the downloads page on the main antlr.org website.
-
-These instructions are mainly for the ANTLR development team,
-though you are free to build ANTLR yourself of course.
-
-Source code Structure
------------------------
-
-The main development branch of ANTLR is stored within the Perforce SCM at:
-
-   //depot/code/antlr/main/...
-
-release branches are stored in Perforce like so:
-
-   //depot/code/antlr/release-3.1.3/...
-
-In this top level directory, you will find a master build file for
-Maven called pom.xml and you will also note that there are a number of
-subdirectories:
-
- tool                  - The ANTLR tool itself
- runtime/Java          - The ANTLR Java runtime
- runtime/X             - The runtime for language target X
- gunit                 - The grammar test tool
- antlr3-maven-plugin   - The plugin tool for Maven allowing Maven
- 		          projects to process ANTLR grammars.
-
-Each of these sub-directories also contains a file pom.xml that
-controls the build of each sub-component (or module in Maven
-parlance).
-
-Build Parameters
------------------
-
-Alongside each pom.xml (other than for the antlr3-maven-plugin), you
-will see that there is a file called antlr.config. This file is called
-a filter and should contain a set of key/value pairs in the same
-manner as Java properties files:
-
-antlr.something="Some config thang!"
-
-When the build of any component happens, any values in the
-antlr.config for the master build file and any values in the
-antlr.config file for each component are made available to the
-build. This is mainly used by the resource processor, which will
-filter any file it finds under: src/main/resources/** and replace any
-references such as ${antlr.something} with the actual value at the
-time of the build.
-
-Building
---------
-
-Building ANTLR is trivial, assuming that you have loaded Maven version
-3.0.3 or better on to your build system and installed it as explained
-here:
-
-http://maven.apache.org/download.html
-
-Note that the ANTLR toolset will ONLY build with version 3.0.3 of Maven
-as of release 3.4.
-
-If you are unfamiliar with Maven (and even if you are), the best
-resource for learning about it is The Definitive Guide:
-
-http://www.sonatype.com/books/maven-book/reference/public-book.html
-
-The instructions here assume that Maven is installed and working correctly.
-
-If this is the first time you have built the ANTLR toolset, you will
-possibly need to install the master pom in your local repository
-(however the build may be able to locate this in the ANTLR snapshot or
-release repository). If you try to build sub-modules on their own (as
-in run the mvn command in the sub directory for that tool, such as
-runtime/Java), and you receive a message that maven cannot find the
-master pom, then execute this in the main (or release) directory:
-
-mvn -N install
-
-This command will install the master build pom in your local maven
-repository (it's ~/.m2 on UNIX) and individual builds of sub-modules
-will now work correctly.
-
-To build then, simply cd into the master build directory
-(e.g. $P4ROOT//code/antlr/main) and type:
-
-mvn -Dmaven.test.skip=true
-
-Assuming that everything is correctly installed and synchronized, then
-ANTLR will build and skip any unit tests in the modules (the ANTLR
-tool tests can take a long time).
-
-This command will build each of the tools in the correct order and
-will create the jar artifacts of all the components in your local
-development Maven repository (which takes precedence over remote
-repositories by default). At the end of the build you should see:
-
-[INFO] ------------------------------------------------------------------------
-[INFO] Reactor Summary:

-[INFO] Total time: 11 seconds
-
-However, unless you are using Maven exclusively in your projects, you
-will most likely want to build the ANTLR Uber Jar, which is an
-executable jar containing all the components that ANTLR needs to build
-and run parsers (note that at runtime, you need only the runtime
-components you use, such as the Java runtime and say stringtemplate).
-
-Because the Uber jar is not something we want to deploy to Maven
-repositories it is built with a special invocation of Maven:
-
-mvn -Dmaven.test.skip=true package assembly:assembly
-
-Note that Maven will appear to build everything twice, which is a
-quirk of how it calculates the dependencies and makes sure it has
-everything packaged up so it can build the uber-jar assembly.
-
-Somewhere in the build output (towards the end), you will find a line
-like this:
-
-[INFO] Building jar: /home/jimi/antlrsrc/code/antlr/main/target/antlr-master-3.4-SNAPSHOT-completejar.jar
-
-This is the executable jar that you need and you can either copy it
-somewhere or, like me, you can create this script (assuming UNIX)
-somewhere in your PATH:
-
-#! /bin/bash
-java -jar ~/antlrsrc/code/antlr/main/target/antlr-master-3.4-SNAPSHOT-completejar.jar $*
-
-Version Numbering
--------------------
-
-The first and Golden rule is that any pom files stored under the main
-branch of the toolset should never be modified to contain a release
-version number. They should always contain a.b.c-SNAPSHOT
-(e.g. 3.1.3-SNAPSHOT). Only release branches should have their pom
-version numbers set to a release version. You can release as many
-SNAPSHOTS as you like, but only one release version. However, release
-versions may be updated with a patch level: 3.1.3-1, 3.1.3-2 and so
-on.
-
-Fortunately, Maven helps us with the version numbering in a number of
-ways. Firstly, the pom.xml files for the various modules do not
-specify a version of the artifacts themselves. They pick up their
-version number from the master build pom.  However, there is a catch,
-because they need to know what version of the parent pom they inherit
-from and so they DO mention the version number. However, this does
-prevent accidentally releasing different versions of sub-modules than
-the master pom describes.
-
-Fortunately once again, Maven has a neat way of helping us change the
-version.  All you need do is check out all the pom.xml files from
-perforce, then modify the <version>a.b.c-SNAPSHOT</version> in the
-master pom. When the version number is correct in the master pom, you
-make sure your working directory is the location of the master pom and
-type:
-
-mvn versions:update-child-modules
-
-This command will then update the child pom.xml files to reflect the
-version number defined in the master pom.xml.
-
-There is unfortunately one last catch here though and that is that the
-antlr3-maven-plugin and the gunit-maven-plugin are not able to use the
-parent pom. The reason for this is subtle but makes sense as doing so
-would create a circular dependency between the ANTLR tool (which uses
-the plugin to build its own grammar files), and the plugins (which
-uses the tool to build grammar files and gunit to test).
-
-This catch-22 situation means that the pom.xml file in the
-antlr3-maven-plugin directory and the one in the gunit-maven-plugin
-directory MUST be updated manually (or we must write a script to do
-this).
-
-Finally, we need to remember that because the tool is dependent on the
-antlr3-maven-plugin and the plugin is itself dependent on the
-tool, that we must manually update the versions of each that they
-reference. So, when we bump the version of the toolset to say
-3.1.4-SNAPSHOT, we need to change the antlr3-maven-plugin pom.xml and
-the gunit-maven-plugin pom.xml to reference that version of the antlr
-tool. The tool itself is always built with the prior released version
-of the plugin, so when we release we must change the main branch of
-the plugin to use the newly released version of the plugin. This is
-covered in the release checklist.
-
-Deploying
-----------
-
-Deploying the tools at the current version is relatively easy, but to
-deploy to the ANTLR repositories (snapshot or release) you must have
-been granted access to the Sonatype OSS repositories' ANTLR login. 
-Few people will have this access of course.
-
-Next, because we do not publish access information for antlr.org, you
-will need to configure the repository server names locally. You do
-this by creating (or adding to) the file:
-
-~/.m2/settings.xml
-
-Which should look like this:
-
-<?xml version="1.0" encoding="UTF-8"?>
-<settings>
-  <servers>
-    <server>
-      <id>sonatype-nexus-snapshots</id>
-      <username>xxxxxxx</username>
-      <password>xxxxxxx</password>
-    </server>
-    <server>
-      <id>sonatype-nexus-staging</id>
-      <username>xxxxxxx</username>
-      <password>xxxxxxx</password>
-    </server>
-  </servers>
-</settings>
-
-When this configuration is in place, you will be able to deploy the components,
-either individually or from the master directory:
-
-mvn -Dmaven.test.skip=true -Ddeplot deploy
-
-You will then see lots of information about checking existing version
-information and so on, and the components will be deployed once you
-supply the ANTLR public key passphrase to sign the jars.
-
-Note that so long as the artifacts are versioned with a.b.c-SNAPSHOT
-then deployment will always be to the development snapshot
-directory. When the artifacts are versioned with a release version
-then deployment will be to the release stahinh repository, which
-will then be mirrored around the world if closed and release.
-The sonatype documentation should be consulted.
-
-Release Checklist
-------------------
-
-Here is the procedure to use to make a release of ANTLR. Note that we
-should really use the mvn release:release command, but the perforce
-plugin for Maven is not commercial quality and I want to rewrite it.
-
-For this checklist, let's assume that the current development version
-of ANTLR is 3.1.3-SNAPSHOT. This means that it will probably (but not
-necessarily) become release version 3.1.3 and that the development
-version will bump to 3.1.4-SNAPSHOT.
-
-0) Run a build of the main branch and check that it is builds and
-   passes as many tests as you want it to.
-
-1) First make a branch from main into the target release
-   directory. Then submit this to perforce. You could change versions
-   numbers before submitting, but doing that in separate stages will
-   keep things sane;
-
---- Use main development branch from here ---
-
-2) Before we deploy the release, we want to update the versions of the
-   development branch, so we don't deploy what is now the new release
-   as an older snapshot (this is not super important, but procedure is
-   good right?).
-
-   Check out all the pom.xml files (and if you are using any
-   antlr.config parameters that must change, then do that too).
-
-3) Edit the master pom.xml in the main directory and change the version from
-   3.1.3-SNAPSHOT to 3.1.4-SNAPSHOT.
-
-4) Edit the pom.xml file for antlr3-maven-plugin under the main
-   directory and change the version from 3.1.3-SNAPSHOT to
-   3.1.4-SNAPSHOT. Do the same for the pom.xml in the
-   gunit-maven-plugin directory.
-
-   Update the pom.xml for the archetype manually too.
-
-5) Now (from the main directory), run the command:
-
-         mvn versions:update-child-modules
-
-      You should see:
-
-         [INFO] [versions:update-child-modules]
-         [INFO] Module: gunit
-         [INFO]   Parent is org.antlr:antlr-master:3.1.4-SNAPSHOT
-         [INFO] Module: runtime/Java
-         [INFO]   Parent is org.antlr:antlr-master:3.1.4-SNAPSHOT
-         [INFO] Module: tool
-         [INFO]   Parent is org.antlr:antlr-master:3.1.4-SNAPSHOT
-
-6) Run a build of the main branch:
-
-         mvn -Dmaven.test.skip=true
-
-       All should be good.
-
-7) Submit the pom changes of the main branch to perforce.
-
-8) Deploy the new snapshot as a placeholder for the next release. It
-   will go to the snapshot repository of course:
-
-	  mvn -N deploy
-          mvn -Dmaven.test.skip=true deploy
-
-9) You are now finished with the main development branch and should change
-   working directories to the release branch you made earlier.
-
---- Use release branch from here ---
-
-10) Check out all the pom.xml files in the release branch (and if you are
-    using any antlr.config parameters that must change, then do that too).
-
-11) Edit the master pom.xml in the release-3.1.3 directory and change
-    the version from 3.1.3-SNAPSHOT to 3.1.3.
-
-12) Edit the pom.xml file for antlr3-maven-plugin under the
-    release-3.1.3 directory and change the version from 3.1.3-SNAPSHOT
-    to 3.1.3. Also change the version of the tool that the this
-    pom.xml references from 3.1.3-SNAPSHOT to 3.1.3 as we are now
-    releasing the plugin of course and it needs to reference the
-    version we are about to release. You will find this reference in
-    the dependencies section of the antlr3-maven-plugin pom.xml. Also
-    change the version references in the pom for gunit-maven-plugin.
-
-13)  Now (from the release-3.1.3 directory), run the command:
-
-           mvn versions:update-child-modules
-
-        You should see:
-
-	[INFO] [versions:update-child-modules]
-	[INFO] Module: gunit
-	[INFO]   Parent was org.antlr:antlr-master:3.1.3-SNAPSHOT,
-	       now org.antlr:antlr-master:3.1.3
-	[INFO] Module: runtime/Java
-	[INFO]   Parent was org.antlr:antlr-master:3.1.3-SNAPSHOT,
-	       now org.antlr:antlr-master:3.1.3
-	[INFO] Module: tool
-	[INFO]   Parent was org.antlr:antlr-master:3.1.3-SNAPSHOT,
-	       now org.antlr:antlr-master:3.1.3
-
-14)  Run a build of the release-3.1.3 branch:
-
-           mvn   # Note I am letting unit tests run here!
-
-        All should be good, or as good as it gets ;-)
-
-15)  Submit the pom changes of the release-3.1.3 branch to perforce.
-
-16)  Deploy the new release (this is it guys, make sure you are happy):
-
-	  mvn -N deploy
-          mvn -Dmaven.test.skip=true deploy
-
-        Note that we must skip the tests as Maven will not let you
-        deploy releases that fail any junit tests.
-
-17) The final step is that we must update the main branch pom.xml for
-     the tool to reference the newly release version of the
-     antlr3-maven-plugin. This is because each release of ANTLR is
-     built with the prior release of ANTLR, and we have just released
-     a new version. Edit the pom.xml for the tool (main/tool/pom.xml)
-     under the main (that's the MAIN branch, not the release branch)
-     and find the dependency reference to the antlr plugin. If you
-     just released say 3.1.3, then the tool should now reference
-     version 3.1.3 of the plugin. Having done this, you should
-     probably rebuild the main branch and let it run the junit
-     tests. Later, I will automate this dependency update as mvn can
-     do this for us.
-
-18)  Having deployed the release to maven, you will want to create the
-     uber jar for the new release, to make it downloadable from the
-     antlr.org website. This is a repeat of the earlier described step
-     to build the uber jar:
-
-       mvn -Dmaven.test.skip=true package assembly:assembly
-
-     MAven will produce the uber jar in the target directory:
-
-	antlr-master-3.1.3-completejar.jar
-
-     And this is the complete jar that can be downloaded from the web site. You
-     may wish to produce an md5 checksum to go with the jar:
-
-     md5sum target/antlr-master-3.1.3-completejar.jar
-     xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx  target/antlr-master-3.1.4-SNAPSHOT-completejar.jar
-
-     The command you just ran will also produce a second jar:
-
-        antlr-master-3.1.3-src.jar
-
-     This is the source code for everythign you just deployed and can
-     be unjarred and built from scratch using the very procedures
-     described here, which means you will now be reading this
-     BUILD.txt file for ever.
-
-19)  Reward anyone around you with good beer.
-
-
-Miscellany
------------
-
-It was a little tricky to get all the interdependencies correct
-because ANTLR builds itself using itself and the maven plugin
-references the ANTLR Tool as well. Hence the maven tool is not a child
-project of the master pom.xml file, even though it is built by it.
-
-An observant person will not that when the assembly:assembly phase is
-run, that it invokes the build of the ANTLR tool using the version of
-the Maven plugin that it has just built, and this results in the
-plugin using the version of ANTLR tool that it has just built. This is
-safe because everything will already be up to date and so we package
-up the version of the tool that we expect, but the Maven plugin we
-deploy will use the correct version of ANTLR, even though there is
-technically a circular dependency.
-
-The master pom.xml does give us a way to cause the build of the ANTLR
-tool to use itself to build itself. This is because in
-dependencyManagement in the master pom.xml, we can reference the
-current version of the Tool and the Maven plugin, even though in the
-pom.xml for the tool itself refers to the previous version of the
-plugin.
-
-What happens is that if we first cd into the tool and maven
-directories and build ANTLR, it will build itself with the prior
-version and this will deploy locally (.m2). We can then clean build
-from the master pom and when ANTLR asks for the prior version of the
-tool, the master pom.xml will override it and build with the interim
-versions we just built manually.
-
-However, strictly speaking, we need a third build where we rebuild the
-tool again with the version of the tool that was built with itself and
-not deploy the version that was built by the version of itself that
-was built by a prior version of itself. I decided that this was not
-particularly useful and complicates things too much. Building with a
-prior version of the tool is fine and if there was ever a need to, we
-could release twice in quick succession.
-
-I have occasionally seen the MAven reactor screw up (or perhaps it is
-the ANTLR tool) when building. If this happens you will see an ANTLR
-Panic - cannot find en.stg message. If this happens to you, then just
-rerun the build and it will eventually work.

+
+INTRODUCTION
+
+Welcome to ANTLR v3!  ANTLR (ANother Tool for Language Recognition) is
+a language tool that provides a framework for constructing
+recognizers, interpreters, compilers, and translators from grammatical
+descriptions containing actions in a variety of target
+languages. ANTLR provides excellent support for tree construction,
+tree walking, translation, error recovery, and error reporting. I've
+been working on parser generators for 25 years and on this particular
+version of ANTLR for 9 years.
+
+You should use v3 in conjunction with ANTLRWorks:
+
+    http://www.antlr.org/works/index.html
+
+and gUnit (grammar unit testing tool included in distribution):
+
+    http://www.antlr.org/wiki/display/ANTLR3/gUnit+-+Grammar+Unit+Testing
+
+The book will also help you a great deal (printed May 15, 2007); you
+can also buy the PDF:

+
+What is ANTLR?
+
+ANTLR stands for (AN)other (T)ool for (L)anguage (R)ecognition
+and generates LL(*) recursive-descent parsers. ANTLR is a language tool
+that provides a framework for constructing recognizers, compilers, and
+translators from grammatical descriptions containing actions.
+Target language list:
+
+http://www.antlr.org/wiki/display/ANTLR3/Code+Generation+Targets
+
+----------------------------------------------------------------------
+
+How is ANTLR v3 different than ANTLR v2?
+
+See "What is the difference between ANTLR v2 and v3?"
+
+    http://www.antlr.org/wiki/pages/viewpage.action?pageId=719
+
+See migration guide:
+
+    http://www.antlr.org/wiki/display/ANTLR3/Migrating+from+ANTLR+2+to+ANTLR+3
+
+----------------------------------------------------------------------
+
+How do I install this damn thing?
+
+You will have grabbed either of these:
+
+	http://antlr.org/download/antlr-3.5-complete-no-st3.jar
+	http://antlr.org/download/antlr-3.5-complete.jar
+
+It has all of the jars you need combined into one. Then you need to
+add antlr-3.5-complete.jar to your CLASSPATH or add to arg list; e.g., on unix:
+
+$ java -cp "/usr/local/lib/antlr-3.5-complete.jar:$CLASSPATH" org.antlr.Tool Test.g
+
+Source + java binaries: Just untar antlr-3.5.tar.gz and you'll get:
+
+antlr-3.5/BUILD.txt
+antlr-3.5/antlr3-maven-plugin
+antlr-3.5/antlrjar.xml
+antlr-3.5/antlrsources.xml
+antlr-3.5/gunit
+antlr-3.5/gunit-maven-plugin
+antlr-3.5/pom.xml
+antlr-3.5/runtime
+antlr-3.5/tool
+antlr-3.5/lib
+
+Please see the FAQ

+ The ANTLR 3 plugin for Maven can generate parsers for any number of grammars in
+ your project.
+

+ files in the directory <<<$\{basedir\}/src/main/antlr3>>> and any additional

+ This can be configured to search other directories using the plugin configuration

-** Configuration parameters
-
-*** report
-
-    If set to true, then after the tool has processed an input grammar file
-    it will report variaous statistics about the parser, such as information
-    on cyclic DFAs, which rules may use backtracking, and so on.
-
-    default-value="false"
-
-*** printGrammar
-
-    If set to true, then the ANTLR tool will print a version of the input
-    grammar which is devoid of any actions that may be present in the input file.
-
-    default-value = "false"
-
-*** debug
-
-     If set to true, then the code generated by the ANTLR code generator will
-     be set to debug mode. This means that when run, the code will 'hang' and
-     wait for a debug connection on a TCP port (49100 by default).
-     
-     default-value="false"
-     
-*** profile
-
-     If set to true, then then the generated parser will compute and report on
-     profile information at runtime.
-     
-     default-value="false"
-     
-*** nfa
-
-     If set to true then the ANTLR tool will generate a description of the nfa
-     for each rule in <a href="http://www.graphviz.org">Dot format</a>
-     
-     default-value="false"
-     
-    protected boolean nfa;
-    
-*** dfa
-
-     If set to true then the ANTLR tool will generate a description of the DFA
-     for each decision in the grammar in <a href="http://www.graphviz.org">Dot format</a>
-     
-     default-value="false"
-     
-*** trace
-
-     If set to true, the generated parser code will log rule entry and exit points
-     to stdout as an aid to debugging.
-     
-     default-value="false"
-     
-*** messageFormat
-
-     If this parameter is set, it indicates that any warning or error messages returned
-     by ANLTR, shoould be formatted in the specified way. Currently, ANTLR supports the
-     built-in formats of antlr, gnu and vs2005.
-
-     default-value="antlr"
-     
-*** verbose
-
-     If this parameter is set to true, then ANTLR will report all sorts of things
-     about what it is doing such as the names of files and the version of ANTLR and so on.
-     
-     default-value="true"
-     
-*** conversionTimeout
-
-     The number of milliseconds ANTLR will wait for analysis of each
-     alternative in the grammar to complete before giving up. You may raise
-     this value if ANTLR gives up on a complicated alt and tells you that
-     there are lots of ambiguties, but you know that it just needed to spend
-     more time on it. Note that this is an absolute time and not CPU time.
-     
-     default-value="10000"
-     
-*** includes
-
-     Provides an explicit list of all the grammars that should
-     be included in the generate phase of the plugin. Note that the plugin
-     is smart enough to realize that imported grammars should be included but
-     not acted upon directly by the ANTLR Tool.
-     
-     Unless otherwise specified, the include list scans for and includes all
-     files that end in ".g" in any directory beneath src/main/antlr3. Note that
-     this version of the plugin looks for the directory antlr3 and not the directory
-     antlr, so as to avoid clashes and confusion for projects that use both v2 and v3 grammars
-     such as ANTLR itself.
-     
-*** excludes
-
-     Provides an explicit list of any grammars that should be excluded from
-     the generate phase of the plugin. Files listed here will not be sent for
-     processing by the ANTLR tool.
-     
-*** sourceDirectory
-
-     Specifies the Antlr directory containing grammar files. For
-     antlr version 3.x we default this to a directory in the tree
-     called antlr3 because the antlr directory is occupied by version
-     2.x grammars.
-
-     <<NB>> Take careful note that the default location for antlr grammars
-     is now <<antlr3>> and NOT <<antlr>>
-
-     default-value="<<<${basedir}/src/main/antlr3>>>"
-     
-*** outputDirectory
-
-     Location for generated Java files. For antlr version 3.x we default
-     this to a directory in the tree called antlr3 because the antlr
-     directory is occupied by version 2.x grammars.
-     
-     default-value="<<<${project.build.directory}/generated-sources/antlr3>>>"
-     
-*** libDirectory
-
-     Location for imported token files, e.g. <code>.tokens</code> and imported grammars.
-     Note that ANTLR will not try to process grammars that it finds in this directory, but
-     will include this directory in the search for .tokens files and import grammars.
-
-     <<NB>> If you change the lib directory from the default but the directory is
-     still under<<<${basedir}/src/main/antlr3>>>, then you will need to exclude
-     the grammars from processing specifically, using the <<<<excludes>>>> option.
-
-     default-value="<<<${basedir}/src/main/antlr3/imports>>>"
-
+ Note that you can create multiple executions, and thus build some grammars with
+ different options to others (such as setting the <<<debug>>> option for
+ instance).

+	/// follow that rule reference on the stack; this amounts to
+	/// computing FIRST of what follows the rule reference in the
+	/// enclosing rule. This local follow set only includes tokens
+	/// from within the rule; i.e., the FIRST computation done by
+	/// ANTLR stops at the end of a rule.
+	//
+	/// EXAMPLE
+	//
+	/// When you find a "no viable alt exception", the input is not
+	/// consistent with any of the alternatives for rule r.  The best
+	/// thing to do is to consume tokens until you see something that
+	/// can legally follow a call to r *or* any rule that called r.
+	/// You don't want the exact set of viable next tokens because the
+	/// input might just be missing a token--you might consume the
+	/// rest of the input looking for one of the missing tokens.
+	///
+	/// Consider grammar:
+	///
+	/// a : '[' b ']'
+	///   | '(' b ')'
+	///   ;
+	/// b : c '^' INT ;
+	/// c : ID
+	///   | INT
+	///   ;
+	///
+	/// At each rule invocation, the set of tokens that could follow
+	/// that rule is pushed on a stack.  Here are the various "local"
+	/// follow sets:
+	///
+	/// FOLLOW(b1_in_a) = FIRST(']') = ']'
+	/// FOLLOW(b2_in_a) = FIRST(')') = ')'
+	/// FOLLOW(c_in_b) = FIRST('^') = '^'
+	///
+	/// Upon erroneous input "[]", the call chain is
+	///
+	/// a -> b -> c
+	///
+	/// and, hence, the follow context stack is:
+	///
+	/// depth  local follow set     after call to rule
+	///   0         <EOF>                    a (from main())
+	///   1          ']'                     b
+	///   3          '^'                     c
+	///
+	/// Notice that ')' is not included, because b would have to have
+	/// been called from a different context in rule a for ')' to be
+	/// included.
+	///
+	/// For error recovery, we cannot consider FOLLOW(c)
+	/// (context-sensitive or otherwise).  We need the combined set of
+	/// all context-sensitive FOLLOW sets--the set of all tokens that
+	/// could follow any reference in the call chain.  We need to
+	/// resync to one of those tokens.  Note that FOLLOW(c)='^' and if
+	/// we resync'd to that token, we'd consume until EOF.  We need to
+	/// sync to context-sensitive FOLLOWs for a, b, and c: {']','^'}.
+	/// In this case, for input "[]", LA(1) is in this set so we would
+	/// not consume anything and after printing an error rule c would
+	/// return normally.  It would not find the required '^' though.
+	/// At this point, it gets a mismatched token error and throws an
+	/// exception (since LA(1) is not in the viable following token
+	/// set).  The rule exception handler tries to recover, but finds
+	/// the same recovery set and doesn't consume anything.  Rule b
+	/// exits normally returning to rule a.  Now it finds the ']' (and
+	/// with the successful match exits errorRecovery mode).
+	///
+	/// So, you can see that the parser walks up call chain looking
+	/// for the token that was a member of the recovery set.
+	///
+	/// Errors are not generated in errorRecovery mode.
+	///
+	/// ANTLR's error recovery mechanism is based upon original ideas:
+	///
+	/// "Algorithms + Data Structures = Programs" by Niklaus Wirth
+	///
+	/// and
+	///
+	/// "A note on error recovery in recursive descent parsers":
+	/// http://portal.acm.org/citation.cfm?id=947902.947905
+	///
+	/// Later, Josef Grosch had some good ideas:
+	///
+	/// "Efficient and Comfortable Error Recovery in Recursive Descent
+	/// Parsers":
+	/// ftp://www.cocolab.com/products/cocktail/doca4.ps/ell.ps.zip
+	///
+	/// Like Grosch I implemented local FOLLOW sets that are combined
+	/// at run-time upon error to avoid overhead during parsing.
+	///
+    BitsetType*	computeErrorRecoverySet();
+
+    /// Compute the context-sensitive FOLLOW set for current rule.
+	/// Documentation below is from the Java runtime.
+	///
+	/// This is the set of token types that can follow a specific rule
+	/// reference given a specific call chain.  You get the set of
+	/// viable tokens that can possibly come next (look ahead depth 1)
+	/// given the current call chain.  Contrast this with the
+	/// definition of plain FOLLOW for rule r:
+	///
+	///  FOLLOW(r)={x | S=>*alpha r beta in G and x in FIRST(beta)}
+	///
+	/// where x in T* and alpha, beta in V*; T is set of terminals and
+	/// V is the set of terminals and non terminals.  In other words,
+	/// FOLLOW(r) is the set of all tokens that can possibly follow
+	/// references to r in///any* sentential form (context).  At
+	/// runtime, however, we know precisely which context applies as
+	/// we have the call chain.  We may compute the exact (rather
+	/// than covering superset) set of following tokens.
+	///
+	/// For example, consider grammar:
+	///
+	/// stat : ID '=' expr ';'      // FOLLOW(stat)=={EOF}
+	///      | "return" expr '.'
+	///      ;
+	/// expr : atom ('+' atom)* ;   // FOLLOW(expr)=={';','.',')'}
+	/// atom : INT                  // FOLLOW(atom)=={'+',')',';','.'}
+	///      | '(' expr ')'
+	///      ;
+	///
+	/// The FOLLOW sets are all inclusive whereas context-sensitive
+	/// FOLLOW sets are precisely what could follow a rule reference.
+	/// For input input "i=(3);", here is the derivation:
+	///
+	/// stat => ID '=' expr ';'
+	///      => ID '=' atom ('+' atom)* ';'
+	///      => ID '=' '(' expr ')' ('+' atom)* ';'
+	///      => ID '=' '(' atom ')' ('+' atom)* ';'
+	///      => ID '=' '(' INT ')' ('+' atom)* ';'
+	///      => ID '=' '(' INT ')' ';'
+	///
+	/// At the "3" token, you'd have a call chain of
+	///
+	///   stat -> expr -> atom -> expr -> atom
+	///
+	/// What can follow that specific nested ref to atom?  Exactly ')'
+	/// as you can see by looking at the derivation of this specific
+	/// input.  Contrast this with the FOLLOW(atom)={'+',')',';','.'}.
+	///
+	/// You want the exact viable token set when recovering from a
+	/// token mismatch.  Upon token mismatch, if LA(1) is member of
+	/// the viable next token set, then you know there is most likely
+	/// a missing token in the input stream.  "Insert" one by just not
+	/// throwing an exception.
+	///
+    BitsetType*	computeCSRuleFollow();

+    /// Compute the current followset for the input stream.
+	///
+    BitsetType*	combineFollows(bool exact);

+	///
+	/// EXTRA TOKEN
+	///
+	/// LA(1) is not what we are looking for.  If LA(2) has the right token,
+	/// however, then assume LA(1) is some extra spurious token.  Delete it
+	/// and LA(2) as if we were doing a normal match(), which advances the
+	/// input.
+	///
+	/// MISSING TOKEN
+	///
+	/// If current token is consistent with what could come after
+	/// ttype then it is ok to "insert" the missing token, else throw
+	/// exception For example, Input "i=(3;" is clearly missing the
+	/// ')'.  When the parser returns from the nested call to expr, it
+	/// will have call chain:
+	///
+	///    stat -> expr -> atom
+	///
+	/// and it will be trying to match the ')' at this point in the
+	/// derivation:
+	///
+	///       => ID '=' '(' INT ')' ('+' atom)* ';'
+	///                          ^
+	/// match() will see that ';' doesn't match ')' and report a
+	/// mismatched token error.  To recover, it sees that LA(1)==';'
+	/// is in the set of tokens that can follow the ')' token
+	/// reference in rule atom.  It can assume that you forgot the ')'.

+
+    Conversions between UTF32, UTF-16, and UTF-8.  Header file.
+
+    Several functions are included here, forming a complete set of
+    conversions between the three formats.  UTF-7 is not included
+    here, but is handled in a separate source file.
+
+    Each of these routines takes pointers to input buffers and output
+    buffers.  The input buffers are const.
+
+    Each routine converts the text between *sourceStart and sourceEnd,
+    putting the result into the buffer between *targetStart and
+    targetEnd. Note: the end pointers are *after* the last item: e.g. 
+    *(sourceEnd - 1) is the last item.
+
+    The return result indicates whether the conversion was successful,
+    and if not, whether the problem was in the source or target buffers.
+    (Only the first encountered problem is indicated.)
+
+    After the conversion, *sourceStart and *targetStart are both
+    updated to point to the end of last text successfully converted in
+    the respective buffers.
+
+    Input parameters:
+	sourceStart - pointer to a pointer to the source buffer.
+		The contents of this are modified on return so that
+		it points at the next thing to be converted.
+	targetStart - similarly, pointer to pointer to the target buffer.
+	sourceEnd, targetEnd - respectively pointers to the ends of the
+		two buffers, for overflow checking only.
+
+    These conversion functions take a ConversionFlags argument. When this
+    flag is set to strict, both irregular sequences and isolated surrogates
+    will cause an error.  When the flag is set to lenient, both irregular
+    sequences and isolated surrogates are converted.
+
+    Whether the flag is strict or lenient, all illegal sequences will cause
+    an error return. This includes sequences such as: <F4 90 80 80>, <C0 80>,
+    or <A0> in UTF-8, and values above 0x10FFFF in UTF-32. Conformant code
+    must check for illegal sequences.
+
+    When the flag is set to lenient, characters over 0x10FFFF are converted
+    to the replacement character; otherwise (when the flag is set to strict)
+    they constitute an error.
+
+    Output parameters:
+	The value "sourceIllegal" is returned from some routines if the input
+	sequence is malformed.  When "sourceIllegal" is returned, the source
+	value will point to the illegal value that caused the problem. E.g.,
+	in UTF-8 when a sequence is malformed, it points to the start of the
+	malformed sequence.

+ *
+ * \remark
+ *  From the java implementation by Terence Parr...
+ *  I did not create a separate AST debugging interface as it would create
+ *  lots of extra classes and DebugParser has a dbg var defined, which makes
+ *  it hard to change to ASTDebugEventListener.  I looked hard at this issue
+ *  and it is easier to understand as one monolithic event interface for all
+ *  possible events.  Hopefully, adding ST debugging stuff won't be bad.  Leave

+
+   b) There is no use in implementing templates here, as all the exceptions are grouped in

+/** \file
+ * Defines the the class interface for an antlr3 INTSTREAM.
+ * 
+ * Certain functionality (such as DFAs for instance) abstract the stream of tokens
+ * or characters in to a steam of integers. Hence this structure should be included
+ * in any stream that is able to provide the output as a stream of integers (which is anything
+ * basically.
+ *
+ * There are no specific implementations of the methods in this interface in general. Though
+ * for purposes of casting and so on, it may be necesssary to implement a function with
+ * the signature in this interface which abstracts the base immplementation. In essence though
+ * the base stream provides a pointer to this interface, within which it installs its
+ * normal match() functions and so on. Interaces such as DFA are then passed the pANTLR3_INT_STREAM
+ * and can treat any input as an int stream. 
+ *
+ * For instance, a lexer implements a pANTLR3_BASE_RECOGNIZER, within which there is a pANTLR3_INT_STREAM.
+ * However, a pANTLR3_INPUT_STREAM also provides a pANTLR3_INT_STREAM, which it has constructed from
+ * it's normal interface when it was created. This is then pointed at by the pANTLR_BASE_RECOGNIZER
+ * when it is intialized with a pANTLR3_INPUT_STREAM.
+ *
+ * Similarly if a pANTLR3_BASE_RECOGNIZER is initialized with a pANTLR3_TOKEN_STREAM, then the 
+ * pANTLR3_INT_STREAM is taken from the pANTLR3_TOKEN_STREAM. 
+ *
+ * If a pANTLR3_BASE_RECOGNIZER is initialized with a pANTLR3_TREENODE_STREAM, then guess where
+ * the pANTLR3_INT_STREAM comes from?
+ *
+ * Note that because the context pointer points to the actual interface structure that is providing
+ * the ANTLR3_INT_STREAM it is defined as a (void *) in this interface. There is no direct implementation
+ * of an ANTLR3_INT_STREAM (unless someone did not understand what I was doing here =;?P

+/** \file
+ * Base interface for any ANTLR3 lexer.
+ *
+ * An ANLTR3 lexer builds from two sets of components:
+ *
+ *  - The runtime components that provide common functionality such as
+ *    traversing character streams, building tokens for output and so on.
+ *  - The generated rules and struutre of the actual lexer, which call upon the
+ *    runtime components.
+ *
+ * A lexer class contains  a character input stream, a base recognizer interface
+ * (which it will normally implement) and a token source interface (which it also
+ * implements. The Tokensource interface is called by a token consumer (such as
+ * a parser, but in theory it can be anything that wants a set of abstract
+ * tokens in place of a raw character stream.
+ *
+ * So then, we set up a lexer in a sequence akin to:
+ *
+ *  - Create a character stream (something which implements ANTLR3_INPUT_STREAM)
+ *    and initialize it.
+ *  - Create a lexer interface and tell it where it its input stream is.
+ *    This will cause the creation of a base recognizer class, which it will
+ *    override with its own implementations of some methods. The lexer creator
+ *    can also then in turn override anything it likes.
+ *  - The lexer token source interface is then passed to some interface that
+ *    knows how to use it, byte calling for a next token.
+ *  - When a next token is called, let ze lexing begin.

-/*  Compute the error recovery set for the current rule.  During

- *  computing FIRST of what follows the rule reference in the
- *  enclosing rule. This local follow set only includes tokens
- *  from within the rule; i.e., the FIRST computation done by
- *  ANTLR stops at the end of a rule.
- *
- *  EXAMPLE
- *
- *  When you find a "no viable alt exception", the input is not
- *  consistent with any of the alternatives for rule r.  The best
- *  thing to do is to consume tokens until you see something that
- *  can legally follow a call to r *or* any rule that called r.
- *  You don't want the exact set of viable next tokens because the
- *  input might just be missing a token--you might consume the
- *  rest of the input looking for one of the missing tokens.
- *
- *  Consider grammar:
- *
- *  a : '[' b ']'
- *    | '(' b ')'
- *    ;
- *  b : c '^' INT ;
- *  c : ID
- *    | INT
- *    ;
- *
- *  At each rule invocation, the set of tokens that could follow
- *  that rule is pushed on a stack.  Here are the various "local"
- *  follow sets:
- *
- *  FOLLOW(b1_in_a) = FIRST(']') = ']'
- *  FOLLOW(b2_in_a) = FIRST(')') = ')'
- *  FOLLOW(c_in_b) = FIRST('^') = '^'
- *
- *  Upon erroneous input "[]", the call chain is
- *
- *  a -> b -> c
- *
- *  and, hence, the follow context stack is:
- *
- *  depth  local follow set     after call to rule
- *    0         <EOF>                    a (from main())
- *    1          ']'                     b
- *    3          '^'                     c
- *
- *  Notice that ')' is not included, because b would have to have
- *  been called from a different context in rule a for ')' to be
- *  included.
- *
- *  For error recovery, we cannot consider FOLLOW(c)
- *  (context-sensitive or otherwise).  We need the combined set of
- *  all context-sensitive FOLLOW sets--the set of all tokens that
- *  could follow any reference in the call chain.  We need to
- *  resync to one of those tokens.  Note that FOLLOW(c)='^' and if
- *  we resync'd to that token, we'd consume until EOF.  We need to
- *  sync to context-sensitive FOLLOWs for a, b, and c: {']','^'}.
- *  In this case, for input "[]", LA(1) is in this set so we would
- *  not consume anything and after printing an error rule c would
- *  return normally.  It would not find the required '^' though.
- *  At this point, it gets a mismatched token error and throws an
- *  exception (since LA(1) is not in the viable following token
- *  set).  The rule exception handler tries to recover, but finds
- *  the same recovery set and doesn't consume anything.  Rule b
- *  exits normally returning to rule a.  Now it finds the ']' (and
- *  with the successful match exits errorRecovery mode).
- *
- *  So, you cna see that the parser walks up call chain looking
- *  for the token that was a member of the recovery set.
- *
- *  Errors are not generated in errorRecovery mode.
- *
- *  ANTLR's error recovery mechanism is based upon original ideas:
- *
- *  "Algorithms + Data Structures = Programs" by Niklaus Wirth
- *
- *  and
- *
- *  "A note on error recovery in recursive descent parsers":
- *  http://portal.acm.org/citation.cfm?id=947902.947905
- *
- *  Later, Josef Grosch had some good ideas:
- *
- *  "Efficient and Comfortable Error Recovery in Recursive Descent
- *  Parsers":
- *  ftp://www.cocolab.com/products/cocktail/doca4.ps/ell.ps.zip
- *
- *  Like Grosch I implemented local FOLLOW sets that are combined
- *  at run-time upon error to avoid overhead during parsing.

-/** Compute the context-sensitive FOLLOW set for current rule.
- *  This is set of token types that can follow a specific rule
- *  reference given a specific call chain.  You get the set of
- *  viable tokens that can possibly come next (lookahead depth 1)
- *  given the current call chain.  Contrast this with the
- *  definition of plain FOLLOW for rule r:
- *
- *   FOLLOW(r)={x | S=>*alpha r beta in G and x in FIRST(beta)}
- *
- *  where x in T* and alpha, beta in V*; T is set of terminals and
- *  V is the set of terminals and nonterminals.  In other words,
- *  FOLLOW(r) is the set of all tokens that can possibly follow
- *  references to r in *any* sentential form (context).  At
- *  runtime, however, we know precisely which context applies as
- *  we have the call chain.  We may compute the exact (rather
- *  than covering superset) set of following tokens.
- *
- *  For example, consider grammar:
- *
- *  stat : ID '=' expr ';'      // FOLLOW(stat)=={EOF}
- *       | "return" expr '.'
- *       ;
- *  expr : atom ('+' atom)* ;   // FOLLOW(expr)=={';','.',')'}
- *  atom : INT                  // FOLLOW(atom)=={'+',')',';','.'}
- *       | '(' expr ')'
- *       ;
- *
- *  The FOLLOW sets are all inclusive whereas context-sensitive
- *  FOLLOW sets are precisely what could follow a rule reference.
- *  For input input "i=(3);", here is the derivation:
- *
- *  stat => ID '=' expr ';'
- *       => ID '=' atom ('+' atom)* ';'
- *       => ID '=' '(' expr ')' ('+' atom)* ';'
- *       => ID '=' '(' atom ')' ('+' atom)* ';'
- *       => ID '=' '(' INT ')' ('+' atom)* ';'
- *       => ID '=' '(' INT ')' ';'
- *
- *  At the "3" token, you'd have a call chain of
- *
- *    stat -> expr -> atom -> expr -> atom
- *
- *  What can follow that specific nested ref to atom?  Exactly ')'
- *  as you can see by looking at the derivation of this specific
- *  input.  Contrast this with the FOLLOW(atom)={'+',')',';','.'}.
- *
- *  You want the exact viable token set when recovering from a
- *  token mismatch.  Upon token mismatch, if LA(1) is member of
- *  the viable next token set, then you know there is most likely
- *  a missing token in the input stream.  "Insert" one by just not
- *  throwing an exception.

-/** We need to combine operations and report invalid operations (like
- *  overlapping replaces that are not completed nested).  Inserts to
- *  same rwIndex need to be combined etc...   Here are the cases:
- *
- *  I.i.u I.j.v								leave alone, nonoverlapping
- *  I.i.u I.i.v								combine: Iivu
- *
- *  R.i-j.u R.x-y.v	| i-j in x-y			delete first R
- *  R.i-j.u R.i-j.v							delete first R
- *  R.i-j.u R.x-y.v	| x-y in i-j			ERROR
- *  R.i-j.u R.x-y.v	| boundaries overlap	ERROR
- *
- *  I.i.u R.x-y.v | i in x-y				delete I
- *  I.i.u R.x-y.v | i not in x-y			leave alone, nonoverlapping
- *  R.x-y.v I.i.u | i in x-y				ERROR
- *  R.x-y.v I.x.u 							R.x-y.uv (combine, delete I)
- *  R.x-y.v I.i.u | i not in x-y			leave alone, nonoverlapping
- *
- *  I.i.u = insert u before op @ rwIndex i
- *  R.x-y.u = replace x-y indexed tokens with u
- *
- *  First we need to examine replaces.  For any replace op:
- *
- * 		1. wipe out any insertions before op within that range.
- *		2. Drop any replace op before that is contained completely within
- *         that range.
- *		3. Throw exception upon boundary overlap with any previous replace.
- *
- *  Then we can deal with inserts:
- *
- * 		1. for any inserts to same rwIndex, combine even if not adjacent.
- * 		2. for any prior replace with same left boundary, combine this
- *         insert with replace and delete this replace.
- * 		3. throw exception if rwIndex in same range as previous replace
- *
- *  Don't actually delete; make op null in list. Easier to walk list.
- *  Later we can throw as we add to rwIndex -> op map.
- *
- *  Note that I.2 R.2-2 will wipe out I.2 even though, technically, the
- *  inserted stuff would be before the replace range.  But, if you
- *  add tokens in front of a method body '{' and then delete the method
- *  body, I think the stuff before the '{' you added should disappear too.
- *
- *  Return a map from token rwIndex to operation.

+ *  enclosing rule. This local follow set only includes tokens
+ *  from within the rule; i.e., the FIRST computation done by
+ *  ANTLR stops at the end of a rule.
+ *
+ *  EXAMPLE
+ *
+ *  When you find a "no viable alt exception", the input is not
+ *  consistent with any of the alternatives for rule r.  The best
+ *  thing to do is to consume tokens until you see something that
+ *  can legally follow a call to r *or* any rule that called r.
+ *  You don't want the exact set of viable next tokens because the
+ *  input might just be missing a token--you might consume the
+ *  rest of the input looking for one of the missing tokens.
+ *
+ *  Consider grammar:
+ *
+ *  a : '[' b ']'
+ *    | '(' b ')'
+ *    ;
+ *  b : c '^' INT ;
+ *  c : ID
+ *    | INT
+ *    ;
+ *
+ *  At each rule invocation, the set of tokens that could follow
+ *  that rule is pushed on a stack.  Here are the various "local"
+ *  follow sets:
+ *
+ *  FOLLOW(b1_in_a) = FIRST(']') = ']'
+ *  FOLLOW(b2_in_a) = FIRST(')') = ')'
+ *  FOLLOW(c_in_b) = FIRST('^') = '^'
+ *
+ *  Upon erroneous input "[]", the call chain is
+ *
+ *  a -> b -> c
+ *
+ *  and, hence, the follow context stack is:
+ *
+ *  depth  local follow set     after call to rule
+ *    0         <EOF>                    a (from main())
+ *    1          ']'                     b
+ *    3          '^'                     c
+ *
+ *  Notice that ')' is not included, because b would have to have
+ *  been called from a different context in rule a for ')' to be
+ *  included.
+ *
+ *  For error recovery, we cannot consider FOLLOW(c)
+ *  (context-sensitive or otherwise).  We need the combined set of
+ *  all context-sensitive FOLLOW sets--the set of all tokens that
+ *  could follow any reference in the call chain.  We need to
+ *  resync to one of those tokens.  Note that FOLLOW(c)='^' and if
+ *  we resync'd to that token, we'd consume until EOF.  We need to
+ *  sync to context-sensitive FOLLOWs for a, b, and c: {']','^'}.
+ *  In this case, for input "[]", LA(1) is in this set so we would
+ *  not consume anything and after printing an error rule c would
+ *  return normally.  It would not find the required '^' though.
+ *  At this point, it gets a mismatched token error and throws an
+ *  exception (since LA(1) is not in the viable following token
+ *  set).  The rule exception handler tries to recover, but finds
+ *  the same recovery set and doesn't consume anything.  Rule b
+ *  exits normally returning to rule a.  Now it finds the ']' (and
+ *  with the successful match exits errorRecovery mode).
+ *
+ *  So, you cna see that the parser walks up call chain looking
+ *  for the token that was a member of the recovery set.
+ *
+ *  Errors are not generated in errorRecovery mode.
+ *
+ *  ANTLR's error recovery mechanism is based upon original ideas:
+ *
+ *  "Algorithms + Data Structures = Programs" by Niklaus Wirth
+ *
+ *  and
+ *
+ *  "A note on error recovery in recursive descent parsers":
+ *  http://portal.acm.org/citation.cfm?id=947902.947905
+ *
+ *  Later, Josef Grosch had some good ideas:
+ *
+ *  "Efficient and Comfortable Error Recovery in Recursive Descent
+ *  Parsers":
+ *  ftp://www.cocolab.com/products/cocktail/doca4.ps/ell.ps.zip
+ *
+ *  Like Grosch I implemented local FOLLOW sets that are combined
+ *  at run-time upon error to avoid overhead during parsing.

+ *  This is set of token types that can follow a specific rule
+ *  reference given a specific call chain.  You get the set of
+ *  viable tokens that can possibly come next (lookahead depth 1)
+ *  given the current call chain.  Contrast this with the
+ *  definition of plain FOLLOW for rule r:
+ *
+ *   FOLLOW(r)={x | S=>*alpha r beta in G and x in FIRST(beta)}
+ *
+ *  where x in T* and alpha, beta in V*; T is set of terminals and
+ *  V is the set of terminals and nonterminals.  In other words,
+ *  FOLLOW(r) is the set of all tokens that can possibly follow
+ *  references to r in *any* sentential form (context).  At
+ *  runtime, however, we know precisely which context applies as
+ *  we have the call chain.  We may compute the exact (rather
+ *  than covering superset) set of following tokens.
+ *
+ *  For example, consider grammar:
+ *
+ *  stat : ID '=' expr ';'      // FOLLOW(stat)=={EOF}
+ *       | "return" expr '.'
+ *       ;
+ *  expr : atom ('+' atom)* ;   // FOLLOW(expr)=={';','.',')'}
+ *  atom : INT                  // FOLLOW(atom)=={'+',')',';','.'}
+ *       | '(' expr ')'
+ *       ;
+ *
+ *  The FOLLOW sets are all inclusive whereas context-sensitive
+ *  FOLLOW sets are precisely what could follow a rule reference.
+ *  For input input "i=(3);", here is the derivation:
+ *
+ *  stat => ID '=' expr ';'
+ *       => ID '=' atom ('+' atom)* ';'
+ *       => ID '=' '(' expr ')' ('+' atom)* ';'
+ *       => ID '=' '(' atom ')' ('+' atom)* ';'
+ *       => ID '=' '(' INT ')' ('+' atom)* ';'
+ *       => ID '=' '(' INT ')' ';'
+ *
+ *  At the "3" token, you'd have a call chain of
+ *
+ *    stat -> expr -> atom -> expr -> atom
+ *
+ *  What can follow that specific nested ref to atom?  Exactly ')'
+ *  as you can see by looking at the derivation of this specific
+ *  input.  Contrast this with the FOLLOW(atom)={'+',')',';','.'}.
+ *
+ *  You want the exact viable token set when recovering from a
+ *  token mismatch.  Upon token mismatch, if LA(1) is member of
+ *  the viable next token set, then you know there is most likely
+ *  a missing token in the input stream.  "Insert" one by just not

+#import "HashMap.h"
+/**
+ * <p>Hash table and linked list implementation of the <tt>Map</tt> interface,
+ * with predictable iteration order.  This implementation differs from
+ * <tt>HashMap</tt> in that it maintains a doubly-linked list running through
+ * all of its entries.  This linked list defines the iteration ordering,
+ * which is normally the order in which keys were inserted into the map
+ * (<i>insertion-order</i>).  Note that insertion order is not affected
+ * if a key is <i>re-inserted</i> into the map.  (A key <tt>k</tt> is
+ * reinserted into a map <tt>m</tt> if <tt>m.put(k, v)</tt> is invoked when
+ * <tt>m.containsKey(k)</tt> would return <tt>true</tt> immediately prior to
+ * the invocation.)
+ * 
+ * <p>This implementation spares its clients from the unspecified, generally
+ * chaotic ordering provided by {@link HashMap} (and {@link Hashtable}),
+ * without incurring the increased cost associated with {@link TreeMap}.  It
+ * can be used to produce a copy of a map that has the same order as the
+ * original, regardless of the original map's implementation:
+ * <pre>
+ * void foo(Map m) {
+ * Map copy = new LinkedHashMap(m);
+ * ...
+ * }
+ * </pre>
+ * This technique is particularly useful if a module takes a map on input,
+ * copies it, and later returns results whose order is determined by that of
+ * the copy.  (Clients generally appreciate having things returned in the same
+ * order they were presented.)
+ * 
+ * <p>A special {@link #LinkedHashMap(NSInteger,float,boolean) constructor} is
+ * provided to create a linked hash map whose order of iteration is the order
+ * in which its entries were last accessed, from least-recently accessed to
+ * most-recently (<i>access-order</i>).  This kind of map is well-suited to
+ * building LRU caches.  Invoking the <tt>put</tt> or <tt>get</tt> method
+ * results in an access to the corresponding entry (assuming it exists after
+ * the invocation completes).  The <tt>putAll</tt> method generates one entry
+ * access for each mapping in the specified map, in the order that key-value
+ * mappings are provided by the specified map's entry set iterator.  <i>No
+ * other methods generate entry accesses.</i> In particular, operations on
+ * collection-views do <i>not</i> affect the order of iteration of the backing
+ * map.
+ * 
+ * <p>The {@link #removeEldestEntry(Map.Entry)} method may be overridden to
+ * impose a policy for removing stale mappings automatically when new mappings
+ * are added to the map.
+ * 
+ * <p>This class provides all of the optional <tt>Map</tt> operations, and
+ * permits null elements.  Like <tt>HashMap</tt>, it provides constant-time
+ * performance for the basic operations (<tt>add</tt>, <tt>contains</tt> and
+ * <tt>remove</tt>), assuming the hash function disperses elements
+ * properly among the buckets.  Performance is likely to be just slightly
+ * below that of <tt>HashMap</tt>, due to the added expense of maintaining the
+ * linked list, with one exception: Iteration over the collection-views
+ * of a <tt>LinkedHashMap</tt> requires time proportional to the <i>size</i>
+ * of the map, regardless of its capacity.  Iteration over a <tt>HashMap</tt>
+ * is likely to be more expensive, requiring time proportional to its
+ * <i>capacity</i>.
+ * 
+ * <p>A linked hash map has two parameters that affect its performance:
+ * <i>initial capacity</i> and <i>load factor</i>.  They are defined precisely
+ * as for <tt>HashMap</tt>.  Note, however, that the penalty for choosing an
+ * excessively high value for initial capacity is less severe for this class
+ * than for <tt>HashMap</tt>, as iteration times for this class are unaffected
+ * by capacity.
+ * 
+ * <p><strong>Note that this implementation is not synchronized.</strong>
+ * If multiple threads access a linked hash map concurrently, and at least
+ * one of the threads modifies the map structurally, it <em>must</em> be
+ * synchronized externally.  This is typically accomplished by
+ * synchronizing on some object that naturally encapsulates the map.
+ * 
+ * If no such object exists, the map should be "wrapped" using the
+ * {@link Collections#synchronizedMap Collections.synchronizedMap}
+ * method.  This is best done at creation time, to prevent accidental
+ * unsynchronized access to the map:<pre>
+ * Map m = Collections.synchronizedMap(new LinkedHashMap(...));</pre>
+ * 
+ * A structural modification is any operation that adds or deletes one or more
+ * mappings or, in the case of access-ordered linked hash maps, affects
+ * iteration order.  In insertion-ordered linked hash maps, merely changing
+ * the value associated with a key that is already contained in the map is not
+ * a structural modification.  <strong>In access-ordered linked hash maps,
+ * merely querying the map with <tt>get</tt> is a structural
+ * modification.</strong>)
+ * 
+ * <p>The iterators returned by the <tt>iterator</tt> method of the collections
+ * returned by all of this class's collection view methods are
+ * <em>fail-fast</em>: if the map is structurally modified at any time after
+ * the iterator is created, in any way except through the iterator's own
+ * <tt>remove</tt> method, the iterator will throw a {@link
+ * ConcurrentModificationException}.  Thus, in the face of concurrent
+ * modification, the iterator fails quickly and cleanly, rather than risking
+ * arbitrary, non-deterministic behavior at an undetermined time in the future.
+ * 
+ * <p>Note that the fail-fast behavior of an iterator cannot be guaranteed
+ * as it is, generally speaking, impossible to make any hard guarantees in the
+ * presence of unsynchronized concurrent modification.  Fail-fast iterators
+ * throw <tt>ConcurrentModificationException</tt> on a best-effort basis.
+ * Therefore, it would be wrong to write a program that depended on this
+ * exception for its correctness:   <i>the fail-fast behavior of iterators
+ * should be used only to detect bugs.</i>
+ *

+ * Doubly-linked list implementation of the {@code List} and {@code Deque}
+ * interfaces.  Implements all optional list operations, and permits all
+ * elements (including {@code null}).
+ * 
+ * <p>All of the operations perform as could be expected for a doubly-linked
+ * list.  Operations that index into the list will traverse the list from
+ * the beginning or the end, whichever is closer to the specified index.
+ * 
+ * <p><strong>Note that this implementation is not synchronized.</strong>
+ * If multiple threads access a linked list concurrently, and at least
+ * one of the threads modifies the list structurally, it <i>must</i> be
+ * synchronized externally.  (A structural modification is any operation
+ * that adds or deletes one or more elements; merely setting the value of
+ * an element is not a structural modification.)  This is typically
+ * accomplished by synchronizing on some object that naturally
+ * encapsulates the list.
+ * 
+ * If no such object exists, the list should be "wrapped" using the
+ * {@link Collections#synchronizedList Collections.synchronizedList}
+ * method.  This is best done at creation time, to prevent accidental
+ * unsynchronized access to the list:<pre>
+ * List list = Collections.synchronizedList(new LinkedList(...));</pre>
+ * 
+ * <p>The iterators returned by this class's {@code iterator} and
+ * {@code listIterator} methods are <i>fail-fast</i>: if the list is
+ * structurally modified at any time after the iterator is created, in
+ * any way except through the Iterator's own {@code remove} or
+ * {@code add} methods, the iterator will throw a {@link
+ * ConcurrentModificationException}.  Thus, in the face of concurrent
+ * modification, the iterator fails quickly and cleanly, rather than
+ * risking arbitrary, non-deterministic behavior at an undetermined
+ * time in the future.
+ * 
+ * <p>Note that the fail-fast behavior of an iterator cannot be guaranteed
+ * as it is, generally speaking, impossible to make any hard guarantees in the
+ * presence of unsynchronized concurrent modification.  Fail-fast iterators
+ * throw {@code ConcurrentModificationException} on a best-effort basis.
+ * Therefore, it would be wrong to write a program that depended on this
+ * exception for its correctness:   <i>the fail-fast behavior of iterators
+ * should be used only to detect bugs.</i>

+ *  R.i-j.u R.x-y.v	| x-y in i-j			ERROR
+ *  R.i-j.u R.x-y.v	| boundaries overlap	ERROR
+ *
+ *  I.i.u R.x-y.v | i in x-y				delete I
+ *  I.i.u R.x-y.v | i not in x-y			leave alone, nonoverlapping
+ *  R.x-y.v I.i.u | i in x-y				ERROR
+ *  R.x-y.v I.x.u 							R.x-y.uv (combine, delete I)
+ *  R.x-y.v I.i.u | i not in x-y			leave alone, nonoverlapping
+ *
+ *  I.i.u = insert u before op @ rwIndex i
+ *  R.x-y.u = replace x-y indexed tokens with u
+ *
+ *  First we need to examine replaces.  For any replace op:
+ *
+ * 		1. wipe out any insertions before op within that range.
+ *		2. Drop any replace op before that is contained completely within
+ *         that range.
+ *		3. Throw exception upon boundary overlap with any previous replace.
+ *
+ *  Then we can deal with inserts:
+ *
+ * 		1. for any inserts to same rwIndex, combine even if not adjacent.
+ * 		2. for any prior replace with same left boundary, combine this
+ *         insert with replace and delete this replace.
+ * 		3. throw exception if rwIndex in same range as previous replace
+ *
+ *  Don't actually delete; make op null in list. Easier to walk list.
+ *  Later we can throw as we add to rwIndex -> op map.
+ *
+ *  Note that I.2 R.2-2 will wipe out I.2 even though, technically, the
+ *  inserted stuff would be before the replace range.  But, if you
+ *  add tokens in front of a method body '{' and then delete the method
+ *  body, I think the stuff before the '{' you added should disappear too.
+ *
+ *  Return a map from token rwIndex to operation.

+ Cut-n-paste from material I'm not using in the book anymore (edit later
+ to make sense):
+
+ Now, how are we going to test these tree patterns against every
+subtree in our original tree?  In what order should we visit nodes?
+For this application, it turns out we need a simple ``apply once''
+rule application strategy and a ``down then up'' tree traversal
+strategy.  Let's look at rule application first.
+
+As we visit each node, we need to see if any of our patterns match. If
+a pattern matches, we execute the associated tree rewrite and move on
+to the next node. In other words, we only look for a single rule
+application opportunity (we'll see below that we sometimes need to
+repeatedly apply rules). The following method applies a rule in a @cl
+TreeParser (derived from a tree grammar) to a tree:
+
+here is where weReferenced code/walking/patterns/TreePatternMatcher.java
+
+It uses reflection to lookup the appropriate rule within the generated
+tree parser class (@cl Simplify in this case). Most of the time, the
+rule will not match the tree.  To avoid issuing syntax errors and
+attempting error recovery, it bumps up the backtracking level.  Upon
+failure, the invoked rule immediately returns. If you don't plan on
+using this technique in your own ANTLR-based application, don't sweat
+the details. This method boils down to ``call a rule to match a tree,
+executing any embedded actions and rewrite rules.''
+
+At this point, we know how to define tree grammar rules and how to
+apply them to a particular subtree. The final piece of the tree
+pattern matcher is the actual tree traversal. We have to get the
+correct node visitation order.  In particular, we need to perform the
+scalar-vector multiply transformation on the way down (preorder) and
+we need to reduce multiply-by-zero subtrees on the way up (postorder).
+
+To implement a top-down visitor, we do a depth first walk of the tree,
+executing an action in the preorder position. To get a bottom-up
+visitor, we execute an action in the postorder position.  ANTLR
+provides a standard @cl TreeVisitor class with a depth first search @v
+visit method. That method executes either a @m pre or @m post method
+or both. In our case, we need to call @m applyOnce in both. On the way
+down, we'll look for @r vmult patterns. On the way up,
+we'll look for @r mult0 patterns.

+/**
+ Cut-n-paste from material I'm not using in the book anymore (edit later
+ to make sense):
+
+ Now, how are we going to test these tree patterns against every
+subtree in our original tree?  In what order should we visit nodes?
+For this application, it turns out we need a simple ``apply once''
+rule application strategy and a ``down then up'' tree traversal
+strategy.  Let's look at rule application first.
+
+As we visit each node, we need to see if any of our patterns match. If
+a pattern matches, we execute the associated tree rewrite and move on
+to the next node. In other words, we only look for a single rule
+application opportunity (we'll see below that we sometimes need to
+repeatedly apply rules). The following method applies a rule in a @cl
+TreeParser (derived from a tree grammar) to a tree:
+
+here is where weReferenced code/walking/patterns/TreePatternMatcher.java
+
+It uses reflection to lookup the appropriate rule within the generated
+tree parser class (@cl Simplify in this case). Most of the time, the
+rule will not match the tree.  To avoid issuing syntax errors and
+attempting error recovery, it bumps up the backtracking level.  Upon
+failure, the invoked rule immediately returns. If you don't plan on
+using this technique in your own ANTLR-based application, don't sweat
+the details. This method boils down to ``call a rule to match a tree,
+executing any embedded actions and rewrite rules.''
+
+At this point, we know how to define tree grammar rules and how to
+apply them to a particular subtree. The final piece of the tree
+pattern matcher is the actual tree traversal. We have to get the
+correct node visitation order.  In particular, we need to perform the
+scalar-vector multiply transformation on the way down (preorder) and
+we need to reduce multiply-by-zero subtrees on the way up (postorder).
+
+To implement a top-down visitor, we do a depth first walk of the tree,
+executing an action in the preorder position. To get a bottom-up
+visitor, we execute an action in the postorder position.  ANTLR
+provides a standard @cl TreeVisitor class with a depth first search @v
+visit method. That method executes either a @m pre or @m post method
+or both. In our case, we need to call @m applyOnce in both. On the way
+down, we'll look for @r vmult patterns. On the way up,
+we'll look for @r mult0 patterns.

+
+	Initial Python3 target, branched from the Python target by Benjamin
+	Niemann, with lots of code cleanup and minor refactoring.
+
+	* CodeGenerator.java, Python3.stg:
+	Generated code now uses set notation for setTest, rather than long
+	conditionals like "a == FOO or a == BAR or 10 <= a <= 12". This is
+	a (slight) performance improvement.
+
+	* tokens.py:
+	Token objects no longer have get/set methods for their attributes as I
+	switched them to use @property instead. The attributes should be accessed
+	directly.
+
+	* tokens.py, Python3.stg:
+	Fix a circular dependency in generated parsers, and give Token objects the
+	ability to return their typeName when asked for it. (The generated
+	recognizer gives Token the mapping from token type to type name.)

+	* PythonTarget.java, dfa.py, exceptions.py, recognizer.py, streams.py:
+	ANTLRStringStream.LA() now returns the character's ordinal and
+	generated lexers operate on integers. Also made various performance
+	tunings.
+
+2007-10-07  Benjamin Niemann  <pink@odahoda.de>
+
+	* main.py, Python.stg (outputFile): Added simple __main__ section to
+	generated code, so (simple) grammars can be executed as standalone
+	script.
+
+	* tree.py (RecognitionException.extractInformationFromTreeNodeStream),
+	exceptions.py (CommonTree): Small bugfixes.
+
+2007-09-30  Benjamin Niemann  <pink@odahoda.de>
+
+	* recognizers.py (TokenSource): Added iterator interface to TokenSource
+	class - and thus to Lexer.
+
+2007-06-27  Benjamin Niemann  <pink@odahoda.de>
+
+	* Python.stg (genericParser, parser, treeParser): Use correct @init
+	action block for tree parsers.
+
+2007-05-24  Benjamin Niemann  <pink@odahoda.de>
+
+	* Python.stg (rule): Added support for @decorate {...} action for
+	parser rules to add decorators to the rule method.
+
+2007-05-18  Benjamin Niemann  <pink@odahoda.de>
+
+	* Python.stg (isolatedLookaheadRangeTest, lookaheadRangeTest): 
+	Minor improvement of generated code (use '<lower> <= <LA> <= <upper>'
+	instead of '<LA> >= <lower> and <LA> <= <upper>').

+1) ABOUT
+========
+
+This is the Python3 package 'antlr3', which is required to use parsers created
+by the ANTLR3 tool. See <http://www.antlr.org/> for more information about
+ANTLR3.
+
+
+2) STATUS
+=========
+
+The Python3 target for ANTLR3 is still in beta. Documentation is lacking, some
+bits of the code is not yet done, some functionality has not been tested yet.
+Also the API might change a bit - it currently mimics the Java implementation,
+but it may be made a bit more pythonic here and there.
+
+WARNING: The runtime library is not compatible with recognizers generated by
+ANTLR versions preceding V3.4.x. If you are an application developer,
+then the suggested way to solve this is to package the correct runtime with
+your application. Installing the runtime in the global site-packages directory
+may not be a good idea.
+Sorry for the inconvenience.
+
+
+3) DOWNLOAD
+===========
+
+This runtime is part of the ANTLR distribution. The latest version can be found
+at <http://www.antlr.org/download.html>.
+
+If you are interested in the latest, most bleeding edge version, have a look at
+the git repository at <http://github.com/antlr/antlr3>.
+
+
+4) INSTALLATION
+===============
+
+Just like any other Python package:
+$ python3 setup.py install
+
+See <http://docs.python.org/inst/> for more information.
+
+
+5) DOCUMENTATION
+================
+
+Documentation (as far as it exists) can be found in the wiki
+<http://www.antlr.org/wiki/display/ANTLR3/Antlr3Python3Target>
+
+
+6) REPORTING BUGS
+=================
+
+Please file bug reports on github: <http://github.com/antlr/antlr3>.
+
+
+7) HACKING
+==========
+
+Only the runtime package can be found here. There are also some StringTemplate
+files in 'src/org/antlr/codegen/templates/Python3/' and some Java code in
+'src/org/antlr/codegen/Python3Target.java' (of the main ANTLR3 source
+distribution).
+
+If there are no directories 'tests' and 'unittests' in 'runtime/Python3', you
+should fetch the latest ANTLR3 version from the perforce depot. See section
+DOWNLOAD.
+You'll need java and ant in order to compile and use the tool.
+Be sure to properly setup your CLASSPATH.
+(FIXME: is there some generic information, how to build it yourself? I should
+point to it to avoid duplication.)
+
+You can then use the commands
+$ python3 setup.py unittest
+$ python3 setup.py functest
+to ensure that changes do not break existing behaviour.
+
+Please send patches as pull requests on github. For larger code contributions
+you'll have to sign the "Developer's Certificate of Origin", which can be
+found on <http://www.antlr.org/license.html> or use the feedback form at
+<http://www.antlr.org/misc/feedback>.

+""" @package antlr3
+@brief ANTLR3 runtime package
+
+This module contains all support classes, which are needed to use recognizers
+generated by ANTLR3.
+
+@mainpage
+
+\\note Please be warned that the line numbers in the API documentation do not
+match the real locations in the source code of the package. This is an
+unintended artifact of doxygen, which I could only convince to use the
+correct module names by concatenating all files from the package into a single
+module file...
+
+Here is a little overview over the most commonly used classes provided by
+this runtime:
+
+@section recognizers Recognizers
+
+These recognizers are baseclasses for the code which is generated by ANTLR3.
+
+- BaseRecognizer: Base class with common recognizer functionality.
+- Lexer: Base class for lexers.
+- Parser: Base class for parsers.
+- tree.TreeParser: Base class for %tree parser.
+
+@section streams Streams
+
+Each recognizer pulls its input from one of the stream classes below. Streams
+handle stuff like buffering, look-ahead and seeking.
+
+A character stream is usually the first element in the pipeline of a typical
+ANTLR3 application. It is used as the input for a Lexer.
+
+- ANTLRStringStream: Reads from a string objects. The input should be a unicode
+  object, or ANTLR3 will have trouble decoding non-ascii data.
+- ANTLRFileStream: Opens a file and read the contents, with optional character
+  decoding.
+- ANTLRInputStream: Reads the date from a file-like object, with optional
+  character decoding.
+
+A Parser needs a TokenStream as input (which in turn is usually fed by a
+Lexer):
+
+- CommonTokenStream: A basic and most commonly used TokenStream
+  implementation.
+- TokenRewriteStream: A modification of CommonTokenStream that allows the
+  stream to be altered (by the Parser). See the 'tweak' example for a usecase.
+
+And tree.TreeParser finally fetches its input from a tree.TreeNodeStream:
+
+- tree.CommonTreeNodeStream: A basic and most commonly used tree.TreeNodeStream
+  implementation.
+  
+
+@section tokenstrees Tokens and Trees
+
+A Lexer emits Token objects which are usually buffered by a TokenStream. A
+Parser can build a Tree, if the output=AST option has been set in the grammar.
+
+The runtime provides these Token implementations:
+
+- CommonToken: A basic and most commonly used Token implementation.
+- ClassicToken: A Token object as used in ANTLR 2.x, used to %tree
+  construction.
+
+Tree objects are wrapper for Token objects.
+
+- tree.CommonTree: A basic and most commonly used Tree implementation.
+
+A tree.TreeAdaptor is used by the parser to create tree.Tree objects for the
+input Token objects.
+
+- tree.CommonTreeAdaptor: A basic and most commonly used tree.TreeAdaptor
+implementation.
+
+
+@section Exceptions
+
+RecognitionException are generated, when a recognizer encounters incorrect
+or unexpected input.
+
+- RecognitionException
+  - MismatchedRangeException
+  - MismatchedSetException
+    - MismatchedNotSetException
+    .
+  - MismatchedTokenException
+  - MismatchedTreeNodeException
+  - NoViableAltException
+  - EarlyExitException
+  - FailedPredicateException
+  .
+.
+
+A tree.RewriteCardinalityException is raised, when the parsers hits a
+cardinality mismatch during AST construction. Although this is basically a
+bug in your grammar, it can only be detected at runtime.
+
+- tree.RewriteCardinalityException
+  - tree.RewriteEarlyExitException
+  - tree.RewriteEmptyStreamException
+  .

+
+    To avoid English-only error messages and to generally make things
+    as flexible as possible, these exceptions are not created with strings,
+    but rather the information necessary to generate an error.  Then
+    the various reporting methods in Parser and Lexer can be overridden
+    to generate a localized error message.  For example, MismatchedToken
+    exceptions are built with the expected token type.
+    So, don't expect getMessage() to return anything.
+
+    Note that as of Java 1.4, you can access the stack trace, which means
+    that you can compute the complete trace of rules from the start symbol.
+    This gives you considerable context information with which to generate
+    useful error messages.
+
+    ANTLR generates code that throws exceptions upon recognition error and
+    also generates code to catch these exceptions in each rule.  If you
+    want to quit upon first error, you can turn off the automatic error
+    handling mechanism using rulecatch action, but you still need to
+    override methods mismatch and recoverFromMismatchSet.
+    
+    In general, the recognition exceptions can track where in a grammar a
+    problem occurred and/or what was the expected input.  While the parser
+    knows its state (such as current input symbol and line info) that
+    state can change before the exception is reported so current token index
+    is computed and stored at exception time.  From this info, you can
+    perhaps print an entire line of input not just a single token, for example.
+    Better to just say the recognizer had a problem and then let the parser
+    figure out a fancy report.

+        Compute the error recovery set for the current rule.  During

+        follow that rule reference on the stack; this amounts to
+        computing FIRST of what follows the rule reference in the
+        enclosing rule. This local follow set only includes tokens
+        from within the rule; i.e., the FIRST computation done by
+        ANTLR stops at the end of a rule.
+
+        EXAMPLE
+
+        When you find a "no viable alt exception", the input is not
+        consistent with any of the alternatives for rule r.  The best
+        thing to do is to consume tokens until you see something that
+        can legally follow a call to r *or* any rule that called r.
+        You don't want the exact set of viable next tokens because the
+        input might just be missing a token--you might consume the
+        rest of the input looking for one of the missing tokens.
+
+        Consider grammar:
+
+        a : '[' b ']'
+          | '(' b ')'
+          ;
+        b : c '^' INT ;
+        c : ID
+          | INT
+          ;
+
+        At each rule invocation, the set of tokens that could follow
+        that rule is pushed on a stack.  Here are the various "local"
+        follow sets:
+
+        FOLLOW(b1_in_a) = FIRST(']') = ']'
+        FOLLOW(b2_in_a) = FIRST(')') = ')'
+        FOLLOW(c_in_b) = FIRST('^') = '^'
+
+        Upon erroneous input "[]", the call chain is
+
+        a -> b -> c
+
+        and, hence, the follow context stack is:
+
+        depth  local follow set     after call to rule
+          0         \<EOF>                    a (from main())
+          1          ']'                     b
+          3          '^'                     c
+
+        Notice that ')' is not included, because b would have to have
+        been called from a different context in rule a for ')' to be
+        included.
+
+        For error recovery, we cannot consider FOLLOW(c)
+        (context-sensitive or otherwise).  We need the combined set of
+        all context-sensitive FOLLOW sets--the set of all tokens that
+        could follow any reference in the call chain.  We need to
+        resync to one of those tokens.  Note that FOLLOW(c)='^' and if
+        we resync'd to that token, we'd consume until EOF.  We need to
+        sync to context-sensitive FOLLOWs for a, b, and c: {']','^'}.
+        In this case, for input "[]", LA(1) is in this set so we would
+        not consume anything and after printing an error rule c would
+        return normally.  It would not find the required '^' though.
+        At this point, it gets a mismatched token error and throws an
+        exception (since LA(1) is not in the viable following token
+        set).  The rule exception handler tries to recover, but finds
+        the same recovery set and doesn't consume anything.  Rule b
+        exits normally returning to rule a.  Now it finds the ']' (and
+        with the successful match exits errorRecovery mode).
+
+        So, you cna see that the parser walks up call chain looking
+        for the token that was a member of the recovery set.
+
+        Errors are not generated in errorRecovery mode.
+
+        ANTLR's error recovery mechanism is based upon original ideas:
+
+        "Algorithms + Data Structures = Programs" by Niklaus Wirth
+
+        and
+
+        "A note on error recovery in recursive descent parsers":
+        http://portal.acm.org/citation.cfm?id=947902.947905
+
+        Later, Josef Grosch had some good ideas:
+
+        "Efficient and Comfortable Error Recovery in Recursive Descent
+        Parsers":
+        ftp://www.cocolab.com/products/cocktail/doca4.ps/ell.ps.zip
+
+        Like Grosch I implemented local FOLLOW sets that are combined
+        at run-time upon error to avoid overhead during parsing.

+        Compute the context-sensitive FOLLOW set for current rule.
+        This is set of token types that can follow a specific rule
+        reference given a specific call chain.  You get the set of
+        viable tokens that can possibly come next (lookahead depth 1)
+        given the current call chain.  Contrast this with the
+        definition of plain FOLLOW for rule r:
+
+         FOLLOW(r)={x | S=>*alpha r beta in G and x in FIRST(beta)}
+
+        where x in T* and alpha, beta in V*; T is set of terminals and
+        V is the set of terminals and nonterminals.  In other words,
+        FOLLOW(r) is the set of all tokens that can possibly follow
+        references to r in *any* sentential form (context).  At
+        runtime, however, we know precisely which context applies as
+        we have the call chain.  We may compute the exact (rather
+        than covering superset) set of following tokens.
+
+        For example, consider grammar:
+
+        stat : ID '=' expr ';'      // FOLLOW(stat)=={EOF}
+             | "return" expr '.'
+             ;

+        atom : INT                  // FOLLOW(atom)=={'+',')',';','.'}
+             | '(' expr ')'
+             ;
+
+        The FOLLOW sets are all inclusive whereas context-sensitive
+        FOLLOW sets are precisely what could follow a rule reference.
+        For input "i=(3);", here is the derivation:
+
+        stat => ID '=' expr ';'
+             => ID '=' atom ('+' atom)* ';'
+             => ID '=' '(' expr ')' ('+' atom)* ';'
+             => ID '=' '(' atom ')' ('+' atom)* ';'
+             => ID '=' '(' INT ')' ('+' atom)* ';'
+             => ID '=' '(' INT ')' ';'
+
+        At the "3" token, you'd have a call chain of
+
+          stat -> expr -> atom -> expr -> atom
+
+        What can follow that specific nested ref to atom?  Exactly ')'
+        as you can see by looking at the derivation of this specific
+        input.  Contrast this with the FOLLOW(atom)={'+',')',';','.'}.
+
+        You want the exact viable token set when recovering from a
+        token mismatch.  Upon token mismatch, if LA(1) is member of
+        the viable next token set, then you know there is most likely
+        a missing token in the input stream.  "Insert" one by just not
+        throwing an exception.

+
+    Useful for dumping out the input stream after doing some
+    augmentation or other manipulations.
+
+    You can insert stuff, replace, and delete chunks.  Note that the
+    operations are done lazily--only if you convert the buffer to a
+    String.  This is very efficient because you are not moving data around
+    all the time.  As the buffer of tokens is converted to strings, the
+    toString() method(s) check to see if there is an operation at the
+    current index.  If so, the operation is done and then normal String
+    rendering continues on the buffer.  This is like having multiple Turing
+    machine instruction streams (programs) operating on a single input tape. :)
+
+    Since the operations are done lazily at toString-time, operations do not
+    screw up the token index values.  That is, an insert operation at token
+    index i does not change the index values for tokens i+1..n-1.
+
+    Because operations never actually alter the buffer, you may always get
+    the original token stream back without undoing anything.  Since
+    the instructions are queued up, you can easily simulate transactions and
+    roll back any changes if there is an error just by removing instructions.
+    For example,
+
+     CharStream input = new ANTLRFileStream("input");
+     TLexer lex = new TLexer(input);
+     TokenRewriteStream tokens = new TokenRewriteStream(lex);
+     T parser = new T(tokens);
+     parser.startRule();
+
+     Then in the rules, you can execute
+        Token t,u;
+        ...
+        input.insertAfter(t, "text to put after t");}
+        input.insertAfter(u, "text after u");}
+        System.out.println(tokens.toString());
+
+    Actually, you have to cast the 'input' to a TokenRewriteStream. :(
+
+    You can also have multiple "instruction streams" and get multiple
+    rewrites from a single pass over the input.  Just name the instruction
+    streams and use that name again when printing the buffer.  This could be
+    useful for generating a C file and also its header file--all from the
+    same buffer:
+
+        tokens.insertAfter("pass1", t, "text to put after t");}
+        tokens.insertAfter("pass2", u, "text after u");}
+        System.out.println(tokens.toString("pass1"));
+        System.out.println(tokens.toString("pass2"));

+    If you don't use named rewrite streams, a "default" stream is used as
+    the first example shows.

+
+        First we need to examine replaces.  For any replace op:
+
+          1. wipe out any insertions before op within that range.
+          2. Drop any replace op before that is contained completely within
+             that range.
+          3. Throw exception upon boundary overlap with any previous replace.
+
+        Then we can deal with inserts:
+
+          1. for any inserts to same index, combine even if not adjacent.
+          2. for any prior replace with same left boundary, combine this
+             insert with replace and delete this replace.
+          3. throw exception if index in same range as previous replace
+
+        Don't actually delete; make op null in list. Easier to walk list.
+        Later we can throw as we add to index -> op map.
+
+        Note that I.2 R.2-2 will wipe out I.2 even though, technically, the
+        inserted stuff would be before the replace range.  But, if you
+        add tokens in front of a method body '{' and then delete the method
+        body, I think the stuff before the '{' you added should disappear too.
+
+        Return a map from token index to operation.

+"""Bootstrap distribute installation
+
+If you want to use setuptools in your package's setup.py, just include this
+file in the same directory with it, and add this to the top of your setup.py::
+
+    from distribute_setup import use_setuptools
+    use_setuptools()
+
+If you want to require a specific version of setuptools, set a download
+mirror, or use an alternate download directory, you can do so by supplying
+the appropriate options to ``use_setuptools()``.
+
+This file can also be run as a script to install or upgrade setuptools.

-INTRODUCTION
-
-Welcome to ANTLR v3!  ANTLR (ANother Tool for Language Recognition) is
-a language tool that provides a framework for constructing
-recognizers, interpreters, compilers, and translators from grammatical
-descriptions containing actions in a variety of target
-languages. ANTLR provides excellent support for tree construction,
-tree walking, translation, error recovery, and error reporting. I've
-been working on parser generators for 20 years and on this particular
-version of ANTLR for 7 years.
-
-You should use v3 in conjunction with ANTLRWorks:
-
-    http://www.antlr.org/works/index.html
-
-and gUnit (grammar unit testing tool included in distribution):
-
-    http://www.antlr.org/wiki/display/ANTLR3/gUnit+-+Grammar+Unit+Testing
-
-The book will also help you a great deal (printed May 15, 2007); you
-can also buy the PDF:
-
-    http://www.pragmaticprogrammer.com/titles/tpantlr/index.html
-
-2nd book, Language Implementation Patterns:
-
-    http://pragprog.com/titles/tpdsl/language-implementation-patterns
-
-See the getting started document:
-
-    http://www.antlr.org/wiki/display/ANTLR3/FAQ+-+Getting+Started
-
-You also have the examples plus the source to guide you.
-
-See the wiki FAQ:
-
-    http://www.antlr.org/wiki/display/ANTLR3/ANTLR+v3+FAQ
-
-and general doc root:
-
-    http://www.antlr.org/wiki/display/ANTLR3/ANTLR+3+Wiki+Home
-
-Please help add/update FAQ entries.
-
-If all else fails, you can buy support or ask the antlr-interest list:
-
-    http://www.antlr.org/support.html

-
-EXAMPLES
-
-ANTLR v3 sample grammars:
-
-    http://www.antlr.org/download/examples-v3.tar.gz
-
-Examples from Language Implementation Patterns:
-
-    http://www.pragprog.com/titles/tpdsl/source_code
-
-Also check out Mantra Programming Language for a prototype (work in
-progress) using v3:
-
-    http://www.linguamantra.org/
-
-----------------------------------------------------------------------
-
-What is ANTLR?
-
-ANTLR stands for (AN)other (T)ool for (L)anguage (R)ecognition
-and generates LL(*) recursive-descent parsers. ANTLR is a language tool
-that provides a framework for constructing recognizers, compilers, and
-translators from grammatical descriptions containing actions.
-Target language list:
-
-http://www.antlr.org/wiki/display/ANTLR3/Code+Generation+Targets
-
-----------------------------------------------------------------------
-
-How is ANTLR v3 different than ANTLR v2?
-
-See "What is the difference between ANTLR v2 and v3?"
-
-    http://www.antlr.org/wiki/pages/viewpage.action?pageId=719
-
-See migration guide:
-
-    http://www.antlr.org/wiki/display/ANTLR3/Migrating+from+ANTLR+2+to+ANTLR+3
-
-----------------------------------------------------------------------
-
-How do I install this damn thing?
-
-Just untar antlr-3.4.tar.gz and you'll get:
-
-antlr-3.4/BUILD.txt
-antlr-3.4/antlr3-maven-plugin
-antlr-3.4/antlrjar.xml
-antlr-3.4/antlrsources.xml
-antlr-3.4/gunit
-antlr-3.4/gunit-maven-plugin
-antlr-3.4/pom.xml
-antlr-3.4/runtime
-antlr-3.4/tool
-antlr-3.4/lib
-
-This is the source and java binaries.  You could grab the
-antlr-3.4-complete.jar file from the website, but it's in lib dir.
-It has all of the jars you need combined into one. Then you need to
-add antlr-3.4-complete.jar to your CLASSPATH or add
-to arg list; e.g., on unix:
-
-$ java -cp "/usr/local/lib/antlr-3.4-complete.jar:$CLASSPATH" org.antlr.Tool Test.g
-
-Please see the FAQ
-
