[boost] [MPL] Is there an "include all" header?

I am looking for a "include all" header for Boost.MPL. Is there such? For the Boost.Preprocessor (having similar structure) there is <boost/preprocessor.hpp> however <boost/mpl.hpp> does not exist. Is it by purpose or just a forgotten feature? Actually I think having such "include all" headers is very convenient especially for larger libraries. (Yes, I know I can write such header by myself and then just use it every time I want to use Boost.MPL however having a "standard one" would be easier I think.) Adam Badura
