Hi

Just a comment, no help sorry!
Some programs behave with command lines argument organized like:

   shell> A -a -b -c -- -x -y -z

where -a -b and -c are options for A
and (after the --) -x -y -z  are for B.

Unfortunately, I don't know if such mechanism is implemented
within program_options. If so, this is what you want and I'm
interested too!

regards
frc
