+=================================
+ Python bindings for bob.measure
+=================================
+
+This package contains a set of Pythonic bindings for Bob's measure packages and
+functionality.
+
+Installation
+------------
+
+Install it through normal means, via PyPI or use ``zc.buildout`` to bootstrap
+the package and run test units.
+
+Documentation
+-------------
+
+You can generate the documentation for this package, after installation, using
+Sphinx::
+
+  $ sphinx-build -b html doc sphinx
+
+This shall place in the directory ``sphinx``, the current version for the
+documentation of the package.
+
+Testing
+-------
+
+You can run a set of tests using the nose test runner::
+
+  $ nosetests -sv xbob.measure
+
+.. warning::
+
+   If Bob <= 1.2.1 is installed on your python path, nose will automatically
+   load the old version of the insulate plugin available in Bob, which will
+   trigger the loading of incompatible shared libraries (from Bob itself), in
+   to your working binary. This will cause a stack corruption. Either remove
+   the centrally installed version of Bob, or build your own version of Python
+   in which Bob <= 1.2.1 is not installed.
+
+You can run our documentation tests using sphinx itself::
+
+  $ sphinx-build -b doctest doc sphinx
+
+You can test overall test coverage with::
+
+  $ nosetests --with-coverage --cover-package=xbob.measure
+
+The ``coverage`` egg must be installed for this to work properly.
+
+Development
+-----------
+
+To develop this package, install using ``zc.buildout``, using the buildout
+configuration found on the root of the package:
+
+  $ python bootstrap.py
+  ...
+  $ ./bin/buildout
+
+Tweak the options in ``buildout.cfg`` to disable/enable verbosity and debug
+builds.

+
+=========
+ C++ API
+=========
+
+The C++ API of ``xbob.io`` allows users to leverage from automatic converters
+for classes in :py:class:`xbob.io`.  To use the C API, clients should first,
+include the header file ``<xbob.io/api.h>`` on their compilation units and
+then, make sure to call once ``import_xbob_io()`` at their module
+instantiation, as explained at the `Python manual
+<http://docs.python.org/2/extending/extending.html#using-capsules>`_.
+
+Here is a dummy C example showing how to include the header and where to call
+the import function:
+
+.. code-block:: c++
+
+   #include <xbob.io/api.h>
+
+   PyMODINIT_FUNC initclient(void) {
+
+     PyObject* m Py_InitModule("client", ClientMethods);
+
+     if (!m) return;
+
+     // imports the NumPy C-API 
+     import_array();
+
+     // imports blitz.array C-API
+     import_blitz_array();
+
+     // imports xbob.core.random C-API
+     import_xbob_io();
+
+   }
+
+.. note::
+
+  The include directory can be discovered using
+  :py:func:`xbob.io.get_include`.
+
+Generic Functions
+-----------------
+
+.. cpp:function:: int PyBobIo_AsTypenum(bob::core::array::ElementType et)
+
+   Converts the input Bob element type into a ``NPY_<TYPE>`` enumeration value.
+   Returns ``NPY_NOTYPE`` in case of problems, and sets a
+   :py:class:`RuntimeError`.
+
+.. cpp:function:: PyObject* PyBobIo_TypeInfoAsTuple (const bob::core::array::typeinfo& ti)
+
+   Converts the ``bob::core::array::typeinfo&`` object into a **new reference**
+   to a :py:class:`tuple` with 3 elements:
+
+     [0]
+         The data type as a :py:class:`numpy.dtype` object
+
+     [1]
+         The shape of the object, as a tuple of integers
+
+     [2]
+         The strides of the object, as a tuple of integers
+
+   Returns ``0`` in case of failure, or a **new reference** to the tuple
+   described above in case of success.
+
+
+Bob File Support
+----------------
+
+.. cpp:type:: PyBobIoFileObject
+
+   The pythonic object representation for a ``bob::io::File`` object.
+
+   .. code-block:: cpp
+
+      typedef struct {
+        PyObject_HEAD
+        boost::shared_ptr<bob::io::File> f;
+      } PyBobIoFileObject;
+
+   .. cpp:member:: boost::shared_ptr<bob::io::File> f
+
+      A pointer to a file being read or written.
+
+.. cpp:type:: PyBobIoFileIteratorObject
+
+   The pythonic object representation for an iterator over a ``bob::io::File``
+   object.
+
+   .. code-block:: cpp
+
+      typedef struct {
+        PyObject_HEAD
+        PyBobIoFileObject* pyfile;
+        Py_ssize_t curpos;
+      } PyBobIoFileIteratorObject;
+
+   .. cpp:member:: PyBobIoFileObject* pyfile
+
+      A pointer to the pythonic representation of a file.
+
+   .. cpp:member:: Py_ssize_t curpos
+
+      The current position at the file being pointed to.
+
+
+Bob HDF5 Support
+----------------
+
+.. cpp:type:: PyBobIoHDF5FileObject
+
+   The pythonic object representation for a ``bob::io::HDF5File`` object.
+
+   .. code-block:: cpp
+
+      typedef struct {
+        PyObject_HEAD
+        boost::shared_ptr<bob::io::HDF5File> f;
+      } PyBobIoHDF5FileObject;
+
+   .. cpp:member:: boost::shared_ptr<bob::io::HDF5File> f
+
+      A pointer to a Bob object being used to read/write data into an HDF5
+      file.
+
+
+.. cpp:function:: int PyBobIoHDF5File_Check(PyObject* o)
+
+   Checks if the input object ``o`` is a ``PyBobIoHDF5FileObject``. Returns
+   ``1`` if it is, and ``0`` otherwise.
+
+
+.. cpp:function:: int PyBobIoHDF5File_Converter(PyObject* o, PyBobIoHDF5FileObject** a)
+
+   This function is meant to be used with :c:func:`PyArg_ParseTupleAndKeywords`
+   family of functions in the Python C-API. It checks the input object to be of
+   type ``PyBobIoHDF5FileObject`` and sets a **new reference** to it (in
+   ``*a``) if it is the case. Returns ``0`` in case of failure, ``1`` in case
+   of success.
+
+Bob VideoReader Support
+-----------------------
+
+.. note::
+
+   The video C-API (and Python) is only available if the package was compiled
+   with FFMPEG or LibAV support.
+
+.. cpp:type:: PyBobIoVideoReaderObject
+
+   The pythonic object representation for a ``bob::io::VideoReader`` object.
+
+   .. code-block:: cpp
+
+      typedef struct {
+        PyObject_HEAD
+        boost::shared_ptr<bob::io::VideoReader> v;
+      } PyBobIoVideoReaderObject;
+
+   .. cpp:member:: boost::shared_ptr<bob::io::VideoReader> v
+
+      A pointer to a Bob object being used to read the video contents
+
+.. cpp:type:: PyBobIoVideoReaderIteratorObject
+
+   The pythonic object representation for an iterator over a
+   ``bob::io::VideoReader`` object.
+
+   .. code-block:: cpp
+
+      typedef struct {
+        PyObject_HEAD
+        PyBobIoVideoReaderObject* pyreader;
+        boost::shared_ptr<bob::io::VideoReader::const_iterator> iter;
+      } PyBobIoFileIteratorObject;
+
+   .. cpp:member:: PyBobIoVideoReaderObject* pyreader
+
+      A pointer to the pythonic representation of the video reader.
+
+   .. cpp:member:: boost::shared_ptr<bob::io::VideoReader::const_iterator> iter
+
+      The current position at the file being pointed to, represented by a
+      formal iterator over the VideoReader.
+
+.. cpp:type:: PyBobIoVideoReaderObject
+
+   The pythonic object representation for a ``bob::io::VideoWriter`` object.
+
+   .. code-block:: cpp
+
+      typedef struct {
+        PyObject_HEAD
+        boost::shared_ptr<bob::io::VideoWriter> v;
+      } PyBobIoVideoWriterObject;
+
+   .. cpp:member:: boost::shared_ptr<bob::io::VideoWriter> v
+
+      A pointer to a Bob object being used to write contents to the video.
