# ==== Options
|

# * <tt>:wait</tt> - Enqueues the job with the specified delay

|
# * <tt>:wait_until</tt> - Enqueues the job at the time specified

# * <tt>:queue</tt> - Enqueues the job on the specified queue
|
|
# * <tt>:priority</tt> - Enqueues the job with the specified priority

# class SiteScrapperJob < ActiveJob::Base
