+# Using TITLE as the test group title, check the generated parser tables
+# and parser for a specified grammar file under a condition labeled by
+# COND-VALUE.
+#
+# TEST-SPEC is a comma-delimited list of attributes of this test.  Each
+# recognized attribute is described below where it is relevant.
+#
+# Insert DECLS and GRAMMAR into the declarations and grammar section of
+# the grammar file.  Insert basic yyerror, yylex, and main function
+# definitions as well.  Hardcode yylex to return the (possibly empty)
+# comma-delimited series of tokens in INPUT followed by token 0.
+#
+# If TEST-SPEC contains the attribute no-xml, then invoke bison using
+# AT_BISON_CHECK_NO_XML.  Otherwise, invoke bison using AT_BISON_CHECK.
+# On the bison command-line, specify `--report=all --defines'.  Check
+# that Bison exits with value 0, has no stdout, and has stderr
+# BISON-STDERR.
+#
+# If TEST-SPEC contains the attribute `last-state', check that the value
+# of TABLES-OR-LAST-STATE is the index of the last state generated for
+# the grammar; in other words, check the number of states (minus one).
+# Otherwise, check that everything in the `.output' file starting with
+# the definition of state 0 is the same as the entire value of
+# TABLES-OR-LAST-STATE.
+#
+# Expand the M4 in OTHER-CHECKS to perform additional checks of the
+# `.output' file, which is named `input.output', and/or grammar file,
+# which is named `input.y'.
+#
+# Finally, compile the generated parser and then run it using
+# AT_PARSER_CHECK with PARSER-EXIT-VALUE, PARSER-STDOUT, and
+# PARSER-STDERR as the 2nd-4th arguments.
+#
+# As a precondition, you must properly double-quote all arguments that

+# condition, in another macro.
