# wait an arbitrary amount of time because smartmon's api is childish;
# ask for failure reports.

# Pretty print the whole thing, in as much as possible, because smartmon's output is fugly to the point of impeding usability.

sleep 1 ## fuckkit, you can't *actually* guess how long the tests are gonna take.  just run it repeatedly until your prayers are answered.
