The overview will appear on top in the "OVERVIEW:" section while the extra help is displayed at the bottom (usually after the big CommonOptionsParser::HelpMessage).
I think both are useful, for example the overview is nicely used in clang-format (short explanation of the tool) and the extra-help has its usefulness as well in cpp11-migrate, we use it to print some simple examples and the common tooling help message. I guess some tools might want both possibilities. http://llvm-reviews.chandlerc.com/D1185 _______________________________________________ cfe-commits mailing list [email protected] http://lists.cs.uiuc.edu/mailman/listinfo/cfe-commits
