+	* gcj.texi (Code Generation):  Document new flags and assert defaults.
+
 	* class.c (assume_compiled_node_struct):  Rename type to
 	class_flag_node_struct, as it is now also used for enable_assertions.
 	Rename assume_compiled_node typedef.  Rename excludep field to value.

+If @var{class-or-package} is a package name, disables generating

+By default, assertions are enabled when generating class files

+@item --enable-assertions[=@var{class-or-package}]
+Generates code to check assertions.  The option is perhaps misnamed,
+as you still need to turn on assertion checking at run-time,
+and we don't support any easy way to do that.
+So this flag isn't very useful yet, except to partially override
+@code{--disable-assertions}.
