CppEphem is a self-contained ephemeris package written in C++. It allows computation of celestial coordinate and date conversions and planet ephemerides by leveraging the Standards of Fundamental Astronomy (SOFA) software (included in the repo). It is C++11 compatible.
The executables converting CIRS -> ICRS and Galactic -> ICRS coordinates are missing. This has a tie in to issue #10 and can probably be resolved in the same pull request.
