'Ephemeris' reads, writes, and interpolates the JPL planetary ephemeris data that is the world standard planetary dataset. It should compile on any machine that uses gcc and supports IEEE floating point arithmetic, and has been tested under GNU/Linux. It uses an included library, gnulliver.c, that automatically handles integer and floating point Big-endian/Little-endian byte swapping to match Big-endian/network order on any computer. gnulliver.c can be used separately under the LGPL 2.1. This is a redesign of JPL's original FORTRAN code, available on JPL's FTP website (ftp://ssd.jpl.nasa.gov/pub/eph/export/), with some added flexibility (including patching some inconsistencies in the original JPL data files). 'Ephemeris' is not associated with JPL or NASA, but just uses JPL's data.
