+Standard structure for a cube
+-----------------------------
+
+A cube is structured as follows:
+
+::
+
+  mycube/
+  |
+  |-- data/
+  |   |-- cubes.mycube.css
+  |   |-- cubes.mycube.js
+  |   `-- external_resources
+  |
+  |-- debian/
+  |   |-- changelog
+  |   |-- compat
+  |   |-- control
+  |   |-- copyright
+  |   |-- cubicweb-mycube.prerm
+  |   `-- rules
+  |
+  |-- entities.py
+  |
+  |-- i18n/
+  |   |-- en.po
+  |   |-- es.po
+  |   `-- fr.po
+  |
+  |-- __init__.py
+  |
+  |-- MANIFEST.in
+  |
+  |-- migration/
+  |   |-- postcreate.py
+  |   `-- precreate.py
+  |
+  |-- __pkginfo__.py
+  |
+  |-- schema.py
+  |
+  |-- setup.py
+  |
+  |-- site_cubicweb.py
+  |
+  |-- hooks.py
+  |
+  |-- test/
+  |   |-- data/
+  |   |   `-- bootstrap_cubes
+  |   |-- pytestconf.py
+  |   |-- realdb_test_mycube.py
+  |   `-- test_mycube.py
+  |
+  `-- views.py
+
+
+We can use subpackages instead of python modules for ``views.py``, ``entities.py``,
+``schema.py`` or ``hooks.py``. For example, we could have:
+
+::
+
+  mycube/
+  |
+  |-- entities.py
+  |-- hooks.py
+  `-- views/
+      |-- forms.py
+      |-- primary.py
+      `-- widgets.py
+
+
+where :
+
+* ``schema`` contains the schema definition (server side only)
+* ``entities`` contains the entities definition (server side and web interface)
+* ``hooks`` contains hooks and/or views notifications (server side only)
+* ``views`` contains the web interface components (web interface only)
+* ``test`` contains tests related to the cube (not installed)
+* ``i18n`` contains message catalogs for supported languages (server side and
+  web interface)
+* ``data`` contains data files for static content (images, css, javascripts)
+  ...(web interface only)
+* ``migration`` contains initialization files for new instances (``postcreate.py``)
+  and a file containing dependencies of the component depending on the version
+  (``depends.map``)
+* ``debian`` contains all the files managing debian packaging (you will find
+  the usual files ``control``, ``rules``, ``changelog``... not installed)
+* file ``__pkginfo__.py`` provides component meta-data, especially the distribution
+  and the current version (server side and web interface) or sub-cubes used by
+  the cube.
+
+
+At least you should have the file ``__pkginfo__.py``.
+
+
+The :file:`__init__.py` and :file:`site_cubicweb.py` files
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The :file:`__pkginfo__.py` file
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+It contains metadata describing your cubes, mostly useful for
+packaging.

+:file:`migration/precreate.py` and :file:`migration/postcreate.py`
