NAME
	libtellurian - Geodesy library

SYNPOSIS
	#include <libtellurian.h>

	Link with -ltellurian -lm.

DESCRIPTION
	libtellurian provides a collection of geodesy functions
	and constants.

	libtellurian always uses meters as the length unit,
	meters per square second as the acceleration unit,
	and degrees for the angle unit, except when the
	function name uses the suffix "_radians", in which
	case the function uses radians instead of degrees.
	All functions that input or output angles have a
	version that uses degress and a version that uses
	radians. Unless otherwise specified, functions that
	use degress convert the input and output to and from
	radians and call the version of the function that
	uses radians.
