+By Oliver Kellogg. Tested on several Ada projects totalling a few ten thousand lines of code. Has tree construction. The parser and tree parser have successfully translated ACES, one of the large standard test suites for Ada compilers.

+
+The Ada tree structure (ada.g) and superclass (ada.tree.g) have
+been tested somewhat due to work on a first real application,
+Ada support in kdevelop (http://www.kdevelop.org)
+
+suggestions on the tree structure are still
+--
+
+You can see the generated tree as follows:
+Define an environment variable, ANTLR_TREE.
+Then run the parser program, and redirect the output to a file.
+
+Example in Bourne shell:
+
+$ export ANTLR_TREE=1
+$ ada my_ada_program.adb > adatree.tmp
+
+This temporary output file will not be nicely readable because
+everything is on a single line. You can get readable output using
+the choptree script:
+
+$ choptree adatree.tmp
+
+If you want to additionally run the generated tree through the
+AdaTreeParserSuper, then define the symbol ANTLR_TREE_WALK:
+
+$ export ANTLR_TREE_WALK=1
+
+This verifies that the tree produced by the AdaParser matches the
+tree expected by the AdaTreeParserSuper.
