-    Returns True if the array is Fortran contiguous but *not* C contiguous.

+    Check if the array is Fortran contiguous but *not* C contiguous.
+    
     This function is obsolete and, because of changes due to relaxed stride
     checking, its return value for the same array may differ for versions
     of NumPy >= 1.10.0 and previous versions. If you only want to check if an
     array is Fortran contiguous use ``a.flags.f_contiguous`` instead.
