+"""
+ This module houses ctypes interfaces for GDAL objects.  The following GDAL
+ objects are supported:
+
+ CoordTransform: Used for coordinate transformations from one spatial
+  reference system to another.
+
+ Driver: Wraps an OGR data source driver.
+  
+ DataSource: Wrapper for the OGR data source object, supports
+  OGR-supported data sources.
+
+ Envelope: A ctypes structure for bounding boxes (GDAL library
+  not required).
+
+ OGRGeometry: Object for accessing OGR Geometry functionality.
+
+ OGRGeomType: A class for representing the different OGR Geometry
+  types (GDAL library not required).
+
+ SpatialReference: Represents OSR Spatial Reference objects.
+
+ The GDAL library will be imported from the system path using the default  
+ library name for the current OS. The default library path may be overridden
+ by setting `GDAL_LIBRARY_PATH` in your settings with the path to the GDAL C 
+ library on your system.  
+
+ GDAL links to a large number of external libraries that consume RAM when 
+ loaded.  Thus, it may desirable to disable GDAL on systems with limited
+ RAM resources -- this may be accomplished by setting `GDAL_LIBRARY_PATH`
+ to a non-existant file location (e.g., `GDAL_LIBRARY_PATH='/null/path'`; 
+ setting to None/False/'' will not work as a string must be given).
