.. note::
While BitBake comes with just the one ``base.bbclass`` file in the
``classes`` directory, it supports class files also being installed
in related directories ``classes-global`` and ``classes-recipe`` and
will automatically search all three directories for a selected class
file.
This means that, in this documentation, when you see a reference to
class files being in the ``classes`` directory, you can interpret that
as meaning in any one of the above three directories.
