+     * Note on strings
+     * ---------------
+     *
+     * String type (type_num == NPY_STRING) does not have fixed

+     * 0. Therefore, for string types, one has to use elsize
+     * argument. For other types, elsize value is ignored.
+     *
+     * NumPy defines the type of a fixed-width string as
+     * dtype('S<width>'). In addition, there is also dtype('c'), that
+     * appears as dtype('S1') (these have the same type_num value),
+     * but is actually different (.char attribute is either 'S' or
+     * 'c', respecitely).
+     *
+     * In Fortran, character arrays and strings are different
+     * concepts.  The relation between Fortran types, NumPy dtypes,
+     * and type_num-elsize pairs, is defined as follows:
+     *
+     * character*5 foo     | dtype('S5')  | elsize=5, shape=()
+     * character(5) foo    | dtype('S1')  | elsize=1, shape=(5)
+     * character*5 foo(n)  | dtype('S5')  | elsize=5, shape=(n,)
+     * character(5) foo(n) | dtype('S1')  | elsize=1, shape=(5, n)
+     * character*(*) foo   | dtype('S')   | elsize=-1, shape=()
+     *
+     * Note about reference counting
+     * -----------------------------
+     *
+     * If the caller returns the array to Python, it must be done with
+     * Py_BuildValue("N",arr).  Otherwise, if obj!=arr then the caller
+     * must call Py_DECREF(arr).
