+"""
+Provides a wrapper for the shapely.lib C API for use in Cython.
+Internally, the shapely C extension uses a PyCapsule to provide run-time access
+to function pointers within the C API.
+
+To use these functions, you must first call the following function in each Cython module:
+`import_shapely_c_api()`
+
+This uses a macro to dynamically load the functions from pointers in the PyCapsule.
+Each C function in shapely.lib exposed in the C API must be specially-wrapped to enable
+this capability.
+
+Segfaults will occur if the C API is not imported properly.
