program-options: Spaces in a value?

What is the best way to specify spaces in a command line value with program_options. I tried putting quotes around the value and program_options couldn't deal with that as far as I could tell. Example: foo --input-file "C:\foo bar.txt" BTW, just saw the new design on the boost home page. Very nice! A great improvement in aeshetics and usability. -- Stephen W.
