Comment (by Sebastian):

 Looks plausible, I could see myself trying it out. A couple of things: The
 cron script should never output a single thing in the case where no errors
 happened, but if an error happened it should always make sure that gets
 reported. There probably wants to be a vacuum somewhere so the database
 file gets shrunk periodically. There should be a protection against
 parallel execution of the script, because that will happen eventually.
 What is the deal with not importing a consensus if it isn't valid anymore?
 I don't understand the logic. The duplicate protection should prevent
 duplicates, so what's the issue?

 For the output format, I thought we had talked about giving a way to
 enumerate which consensuses were missing. Maybe that could at least be an
 optional command? Also, instead of
 {{{
 n-inputs <number of consesuses parsed> <number of months considered>
 }}}

 maybe

 {{{
 n-inputs <number of consensuses parsed> <number of all consensuses in
 voting period> <number of months considered>
 }}}

 is more appropriate/easier to understand? Because otherwise "how many
 hours is a month" becomes an issue.

 What happens with consensuses generated at the half-hour mark? Can they
 accidentally get added, and if they do, do they distort results?
