module Plugins
# Includes the Shrine `derivatives` plugin with some configuration, and
# extra features. The metadata for shrine derivatives is stored in the same
# JSON as the main file.
#
# * default kithe storage location of :kithe_derivatives
#
# * nice metadata["filename"] for derivatives, instead of default shrine fairly
# random (filename ends up used by default in content-disposition headers when delivered)
#
# * Includes kithe_persisted_derivatives with #add_persisted_derivatives
# and #create_persisted_derivatives methods for concurrency-safe
# derivative persisting.
