"""Cron script to generate usage notifications for instances neither created
nor destroyed in a given time period.
Together with the notifications generated by compute on instance
create/delete/resize, over that ime period, this allows an external
system consuming usage notification feeds to calculate instance usage
for each tenant.
Time periods are specified like so:
<number>[mdy]
1m = previous month. If the script is run April 1, it will generate usages
for March 1 thry March 31.
3m = 3 previous months.
90d = previous 90 days.
1y = previous year. If run on Jan 1, it generates usages for
Jan 1 thru Dec 31 of the previous year.
