+is basically a collection of geographic objects like maps, layers,
+datasources, features, and geometries.  At its core is a C++ shared library
+providing algorithms and patterns for spatial data access and visualization.
+The library does not rely on any specific windowing system and can be deployed
+to any server environment.  It is intended to play fair in a multi-threaded
+environment and is aimed primarily, but not exclusively, at web-based
+development.")
