Creating a new cube from scratch

--------------------------------

Let's start by creating the cube environment in which we will develop ::

  # use cubicweb-ctl to generate a template for the cube

  # will ask some questions, most with nice default

  cubicweb-ctl newcube mycube

  # makes the cube source code managed by mercurial

  hg init

  hg add .

  hg ci

If all went well, you should see the cube you just created in the list

returned by ``cubicweb-ctl list`` in the  *Available cubes* section.

If not, please refer to :ref:`ConfigurationEnv`.

To reuse an existing cube, add it to the list named

``__depends_cubes__`` which is defined in :file:`__pkginfo__.py`.

This variable is used for the instance packaging (dependencies handled

by system utility tools such as APT) and to find used cubes when the

database for the instance is created.
