################################
Relationship type constant names
################################


The following names are defined in the :mod:`opc.constants` module to allow
relationship types to be referenced using an identifier rather than a literal
value.

The following import statement makes these available in a module::

    from opc.constants import RELATIONSHIP_TYPE as RT

A relationship type may then be referenced as a member of ``RT`` using dotted
notation, for example::

    rel.reltype = RT.SLIDE_LAYOUT

The relationship type names are determined by transforming the trailing text
of the relationship type string to upper snake case and replacing illegal
Python identifier characters (the occasional hyphen) with an underscore.
