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.
