Hi all, I'm using <boost/program_options.hpp> to parse a command line. It has only two positional arguments. However, I don't see how to generate the help without the name of the variable. I'd like to get the following output: MyProg.exe Param1 [Param2] where Param1 is the first parameter Param2 (=200) is the second parameter (optional) Any ideas would be appreciated.
