Hi! I have already asked this question about a month ago. But it wasn't answered and I suppose to repeat. I cannot find in docs how to create named vales for producing output like shown in this example from docs: $bin/gcc/debug/multiple_sources --help Allows options: Generic options: -v [ --version ] : print version string --help : produce help message Configuration: --optimization n : optimization level -I [ --include-path ] path : include path The "--include-path" option shown above has "path" parameter, what I have is "arg". Also I don't understand how to restrict hidden values. For example I want command "myutil --help restrict this" to throw an exception because of "restrict" and "this" but it doesn't do it. Regards. Igor.
