I'm sure Fred didn't mean to leave this impression, but I just want to
clarify something here that could be misinterpreted. Documenting
concepts is not really "a tempate metaprogramming convention;" it's a
convention that was started by Stepanov et. al. when the STL was
invented, and is appropriate for all generic libraries. Aleksey used
it to document the MPL because it was appropriate there, too. That
means almost any library with templates in its public interface should
have concept documentation.
