Namespace ===================== The default namespace ------------------------- The families and variables contained in these structure files are ordered, by default, in the `rougail` namespace. It is possible to change the name of this namespace with the :term:`variable namespace ` parameter of the :doc:`configuration `. This namespace is a bit special, it can access variables in another namespace. The extra structure files --------------------------- An extra is a different namespace. The idea is to be able to classify the variables by theme. Extra namespaces must be declared :doc:`when configuring Rougail `. In this namespace we cannot access variables from another `extra` namespace. On the other hand, it is possible to access the variable of the default namespace.
