# For Heroku deployments, this will be superseded by the Heroku scheduler (for
# more info see: https://devcenter.heroku.com/articles/scheduler).
# Any changes here should be implemented in lib/tasks/scheduler.rake!

# Example:
#
# set :cron_log, "/path/to/my/cron_log.log"
#
# every 2.hours do
#   command "/usr/bin/some_great_command"
#   runner "MyModel.some_method"
#   rake "some:great:rake:task"
# end
#
# every 4.days do
#   runner "AnotherModel.prune_old_records"
# end
