[Boost-users] [program_options] Specify the same flag multiple times

I would like to be able to specify a flag multiple times on the command line.  
For instance, imagine a program that has two levels of verbosity.  The first 
level of verbosity would be activated by specifying "-v" on the command line, 
and the second level of verbosity would be activated by specifying "-vv" 
or "-v -v" on the command line.

Display verbose print statements:
   myProgram -v

Display very verbose print statements:
   myProgram -vv

In digging through the documentation, it is not evident to me how I can 
accomplish this with Boost.Program_Options.  Any help would be appreciated.

Thanks,
Justin
