-- Examples require lens package in addition to this packackage's dependencies.
-- When using sandbox it is possible to use `cabal repl` to test examples by
-- using following command:
--
--     cabal repl --ghc-options='-iexample -package lens -package optparse-applicative'
--
-- It's also possible to use `stack repl`:
--
--     stack repl --ghci-options='-package lens -package optparse-applicative'
