How to Reproduce

For instance, to reproduce Figure 7:

$ reprounzip vagrant setup query_execution_time.rpz query_execution_time/
$ reprounzip vagrant run query_execution_time/
$ reprounzip vagrant download query_execution_time/ scan_duration.png
$ reprounzip vagrant download query_execution_time/ scan_duration_updates.png

You can’t perform that action at this time.
