%description

SuperNOVAS is a C/C++ astronomy library, providing high-precision astronomical 
calculations such as one might need for running an observatory or a precise 
planetarium program. It is a fork of the Naval Observatory Vector Astrometry 
Software (NOVAS) C version 3.1, providing bug fixes and making it easier to 
use overall.

The main goals of SuperNOVAS are to improve usability, add new features, 
promote best practices, and provide accessible documentation -- all while 
retaining 100% API compatibility with NOVAS C 3.1. Thus, if you have written 
code for NOVAS C 3.1, you can build it with SuperNOVAS also.

SuperNOVAS is entirely free to use without licensing restrictions. Its source 
code is compatible with the C90 standard, and hence should be suitable for old 
and new platforms alike. It is light-weight and easy to use, with full support 
for the IAU 2000/2006 standards for sub-micro-arc-second position 
calculations.

%package cio-data
Summary:		CIO location data for the SuperNOVAS C/C++ astronomy library
BuildArch: 		noarch
Requires:		%{name} = %{version}-%{release}

%description cio-data
Optional CIO location vs GCRS lookup table. This file is not normally required
for the operation of the library. It is needed only if the user explicitly needs
to know the location of the CIO vs GCRS, rather than w.r.t. the equinox of date.
Applications that require CIO location w.r.t. the GCRS should depend on this
sub-package

%package devel
Summary:		C development files for the SuperNOVAS C/C++ astronomy library
Requires:		%{name}%{_isa} = %{version}-%{release}

%description devel
This sub-package provides C headers and non-versioned shared library symbolic 
links for the SuperNOVAS C/C++ library.


%package doc
Summary:		Documentation for the SuperNOVAS C/C++ astronomy library
BuildArch:		noarch
Requires:		%{name} = %{version}-%{release}

%description doc
This package provides man pages and HTML documentation for the SuperNOVAS 
C/C++ astronomy library.
