I don't see why the API needs to be changed to support automatically
generating help messages. Extended yes, but not changed.
This is a simple idea:
uint timeout;
getopt(args, "timeout|t", &timeout).help("Set the timeout");
This interface assumes you can call "getopt" multiple times and call
"getopt" once per flag.
Alternatively pass in some form of options struct or similar:
struct Options
{
string help;
}
auto options = Options("Set the timeout");
uint timeout;
getopt(args, "timeout|t", &timeout, options);
