Is it possible to get the BoostBook/Doxygen documentation system to include my commentary? This is the header file #include <boost/child/detail/pipe_mode.hpp> namespace boost { namespace child { /// A stateless class providing constants and typenames. struct pipes_base { /// A type used to specify how to communciate with the child process. typedef detail::pipe_mode pipe_mode; /// Write to the child's standard input stream. static const pipe_mode child_stdin = pipe_mode(1); /// Read from the child's standard output stream. static const pipe_mode child_stdout = pipe_mode(2); /// Read from the child's standard error stream. static const pipe_mode child_stderr = pipe_mode(4); /// Redirect the child's stderr to its stdout. static const pipe_mode redirect_child_stderr = pipe_mode(8); /// No pipes are to be used. static const pipe_mode no_pipes = pipe_mode(16); }; } // namespace child } // namespace boost And below is the generated documentation. See how all the descriptions of the constants have dissappeared. Also see how the typedef has been 'modified'. Regards, Angus Struct pipes_base boost::child::pipes_base ? A stateless class providing constants and typenames. Synopsis struct pipes_base { // types typedef unspecified pipe_mode; // A type used to specify how to communciate with the child process. static const pipe_mode child_stdin; static const pipe_mode child_stdout; static const pipe_mode child_stderr; static const pipe_mode redirect_child_stderr; static const pipe_mode no_pipes; };
