Volodya,

I get boost::program_options::invalid_command_line_syntax.  I guess my question
is this:

If I want to make it so that if the user does not provide a value for the
option, do I need to basically handle that in the catch block of the exception
handling, or is there some other way of doing it upfront?

Thanks,
-Andy
