+/// <b>Future Plans and Compatibility Notes</b>
+///
+/// Currently, benchmark developers need to write supplemental code that is
+/// not directly related to benchmarks (such as \c %main()) by hand.
+/// It would be better if we could minimize such development overhead.
+/// In future versions we may provide a common \c %main() function and
+/// option parsers, thereby allowing the developer to only write the benchmark
+/// classes and invoke them, just like what various unit test frameworks do.
+///
+/// If and when we implement it, some existing benchmark cases may need to be
+/// adjusted.
