[Boost-users] [Boost users] [Program_options] Is Boost.Program_options available as a header?

Hi Boost users, I'm quite new to boost. I have written a program using the Boost Program Options library. In order to compile it I have to link with the boost program options library. I would like to run my program on a computer which only has access to boost headers. I was wondering if the program options library is available as a header only? If not, it would be interesting to know the reason for that :) Best, Matija
