module Vedeu
# Subclassing Vedeu::View will allow Vedeu to call your #render method.
# This method should contain attributes required to build a view or views.
# These attributes will be added to the back buffer of each interface
# mentioned, to be rendered upon next refresh.

# @deprecated May disappear in 0.3.0. Prefer {Vedeu::API#render} instead.
