Description:
The AST library provides a comprehensive range of facilities for attaching
world coordinate systems to astronomical data, for retrieving and interpreting
that information and for generating graphical output based on it. Its main
selling points are:

    Ease of use.
    Facilities for generating plots of generalised non-linear, potentially
        discontinuous 2-D or 3-D coordinate systems, with detailed control of
        the appearance of the plot.
    Facilities for converting transparently between different coordinate
        systems, including a wide range of celestial, spectral and time
        coordinate systems.
    Facilities for searching a general collection of connected coordinate
        systems for a coordinate system with any given set of characteristics.
    Allows code for handling WCS information to be written in a general way
        without regard to the specific nature of the coordinate systems being
        handled (i.e. whether they represent sky positions, spectral positions,
        focal plane positions, pixel positions, etc).
    Flexible system for saving and retrieving WCS information, including (but
        not limited to) a range of different popular FITS descriptions.
    Written in C but has interfaces for C, Fortran, Java (via JNI), Perl, and
        UNIX shell.
    Extensive documentation.
