[Boost-users] [units] Units-only git submodule usage

Hello, Here's a crazy question. I am exploring what to do with a simulation calculator, for dimensional analysis, dimensional safety, and potentially adopting Boost.Unit to help with that. What with the decomposition of Boost into Git Submodules, and since Boost.Units is header only (yes?), do I really need the whole library, or I could just adopt a Boost.Unit submodule and include it as appropriate? Thanks in advance... Best regards, Michael Powell
