I'm just trying to use Boost.Program_options in an application and during my implementation, it appears a couple of questions: - Is it possible to introduce more than one "multitoken" options in command line? I didn't see any limitation in the documentation but my sample hereafter seems to prove that yes. - If the answer to the first question is yes, then how I can handle this feature? I seemed that with the older version, 1.32, this feature was supported? Thanks in advance.
