    Ephemeris Source Code
    From: Dan Allen

    contains quite a few interesting programs that are long-term almanacs
    based on JPL's DE200 and such.
    
    Here is a short summary of one program available on this web site:
    
    ---
    
    aa-55.zip: Self-contained ephemeris calculator; size 383 KB.
    C program computes ephemerides of Sun, Moon, planets, comets, and stars
    using rigorous reduction methods from the _Astronomical Almanac_ and
    related sources. Includes PLAN404 series (see below) for positions of
    the planets, and a long-term extension of modern Lunar theory for the
    Moon's position. Reads ASCII file catalogues of stars and orbital
    elements. Displays all adjustments as it finds local azimuth and
    elevation, rise and set times, etc. Windows or MSDOS (Microsoft and
    Borland), Unix, VAX make files. Archive includes MSDOS executable
    program. Latest update 2003-05-03.

    I downloaded the above program, unpacked it, and did a "make" in Mac OS
    X and it builds and runs just fine.
    
    He (Steve Moshier) also has done analysis of Meeus' algorithms and
    such.  There is a lot of useful code and information on this site
    worthy of examination!
