# frozen_string_literal: true

# This concern is created to handle repository actions.
# It should be include inside any object capable
# of directly having a repository, like project or snippet.
#
# It also includes `Referable`, therefore the method
# `to_reference` should be overridden in case the object
# needs any special behavior.
