Yes, you have two approaches.

1. Specify a custom way to parse fs::path to Boost.program_options 
See http://boost.org/doc/html/program_options/howto.html#id2716150
for an example.

2. Convince Beman Dawes, the author of Boost.Filesystem, that adding
operator>> for paths is a good idea. Personally, I don't see any reason why
it should not work -- if I want to save/load something containing
boost::fs::path, working operator>> would be a plus.
