+@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}.
