Use a command line style that does not think '-3' is an option. Multitoken options are BAD, exactly because of these ambiguities.

Usually what I'm trying to do is input a 3d coordinate. I have tried to do
this:
vgl_point_3d<double> Point;
desc.add_options()
("point,p", po::value (&Point)->default_value(vgl_point_3d<double>(0.0, 0.0, 0.0)), "set point") But when I run the program with:
./Test --point 1 2 3
I get:
what(): in option 'point': invalid option value '1'
(the input operator is properly defined, ie
vgl_point_3d<double> P;
std::cin >> P;
works as expected).
This is why I resorted to a multitoken option. The other option I can think
of is --x 1 --y 2 --z 3, is that what you are recommending?
Thanks,
Dave
