Menubars
===============

Menubars are defined via a declarative XML syntax. Modifications
view Nasal APIs at runtime are also possible, but should be done with care,
to avoid incompatibilities.

.. note::
    Familiarty with the XML syntax for :doc:`expressions </reference/xml-reference/expression/index>`,
    :doc:`conditions </reference/xml-reference/condition/index>` and
    :doc:`bindings </reference/xml-reference/binding>`
    is assumed, since these are used to drive most functionality.
