You know that time when somebody had a problem with a system you wrote years ago, and it has taken you an hour to try to remember how to even call it, because the documentation and code didn't get migrated from svn to git, and the svn server has been shut down for some reason, and the admin is out today, and the last time you had the code was three machines ago, so you're trying to gleam what needs to be done to just call the stupid thing from log files set to 'error'?

That time is now.
