/* Base declarations and includes */
/*
* pgSphere is an extra module for PostgreSQL which adds spherical data types. It provides:
*
* - input and output of data
* - containing, overlapping, and other operators
* - various input and converting functions and operators
* - circumference and area of an object
* - spherical transformation
* - indexing of spherical data types
* - several input and output formats
*
* Hence, you can do a fast search and analysis for objects with spherical
* attributes as used in geographical, astronomical, or other applications
* using PostgreSQL. For instance, you can manage data of geographical
* objects around the world and astronomical data like star and other
* catalogs conveniently using an SQL interface.
*
* The aim of pgSphere is to
* provide uniform access to spherical data. Because PostgreSQL itself
* supports a lot of software interfaces, you can now use the same database
* with different utilities and applications.
