+
+        The contents of the cell are written to a `.pyx` file in the
+        directory `IPYTHONDIR/cython` using a filename with the hash of the
+        code. This file is then cythonized and compiled. The resulting module
+        is imported and all of its symbols are injected into the user's
+        namespace. The usage is similar to that of `%%cython_pyximport` but
+        you don't have to pass a module name::
+
+            %%cython
+            def f(x):
+                return 2.0*x
+
+        To compile OpenMP codes, pass the required  `--compile-args`
+        and `--link-args`.  For example with gcc::
+
+            %%cython --compile-args=-fopenmp --link-args=-fopenmp
+            ...
+
+        To enable profile guided optimisation, pass the ``--pgo`` option.
+        Note that the cell itself needs to take care of establishing a suitable
+        profile when executed. This can be done by implementing the functions to
+        optimise, and then calling them directly in the same cell on some realistic
+        training data like this::
+
+            %%cython --pgo
+            def critical_function(data):
+                for item in data:

+            for _ in range(100):
+                critical_function(some_typical_data)
+
+        In Python 3.5 and later, you can distinguish between the profile and
+        non-profile runs as follows::
