+""" @package google.appengine._internal.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
+  .
