[Boost-users] Header only libraries, why not all?

Subject: [Boost-users] Header only libraries, why not all?

Header-only libraries are great as that eliminates the need for
building the libraries and then linking with them. But not all
libraries in boost are header only, which is an inconvenience.

Is this only because of 'legacy', and with time all libraries will
move towards being header only? Or is there some technical requirement
due to which some libraries just can't ever be header-only?
