+"""Cron script to generate usage notifications for instances existing
+   during the audit period.
+
+   Together with the notifications generated by compute on instance
+   create/delete/resize, over that time period, this allows an external
+   system consuming usage notification feeds to calculate instance usage
+   for each tenant.
+
+   Time periods are specified as 'hour', 'month', 'day' or 'year'
+
+   hour = previous hour. If run at 9:07am, will generate usage for 8-9am.
+   month = previous month. If the script is run April 1, it will generate
+           usages for March 1 through March 31.
+   day = previous day. if run on July 4th, it generates usages for July 3rd.
+   year = previous year. If run on Jan 1, it generates usages for
+        Jan 1 through Dec 31 of the previous year.
