+The Python C API
+================
+
+The C API is divided into these sections:
+
+1. ``Include/``: Limited API
+2. ``Include/cpython/``: CPython implementation details
+3. ``Include/cpython/``, names with the ``PyUnstable_`` prefix: API that can
+   change between minor releases
+4. ``Include/internal/``, and any name with ``_`` prefix: The internal API
+
+Information on changing the C API is available `in the developer guide`_

+the following defines used by the different modules:
+
+STRINGLIB_CHAR
+
+    the type used to hold a character (char or Py_UNICODE)
+
+STRINGLIB_GET_EMPTY()
+
+    returns a PyObject representing the empty string, only to be used if
+    STRINGLIB_MUTABLE is 0. It must not be NULL.
+
+Py_ssize_t STRINGLIB_LEN(PyObject*)
+
+    returns the length of the given string object (which must be of the
+    right type)
+
+PyObject* STRINGLIB_NEW(STRINGLIB_CHAR*, Py_ssize_t)
+
+    creates a new string object
+
+STRINGLIB_CHAR* STRINGLIB_STR(PyObject*)
+
+    returns the pointer to the character data for the given string
+    object (which must be of the right type)
+
+int STRINGLIB_CHECK_EXACT(PyObject *)
+
+    returns true if the object is an instance of our type, not a subclass
+
+STRINGLIB_MUTABLE
+
+    must be 0 or 1 to tell the cpp macros in stringlib code if the object
+    being operated on is mutable or not
