this is a helper script to send emails to people who've not logged in
for a while (currently hard-coded to "since 2023-01-01"). It also sends
weekly reminders to admins giving the current number of unused accounts.

It is in $PATH for all normal users; for usage, invoke it with --help,
or just see the email it send to admin@.

Hallo ~|displayname|!
Wir haben schon lange (seit über einem Jahr; dein letzter Login war um ~|last-login|)
nichts mehr von dir gehört und würden demnächst deinen Account löschen wollen.
Solltest du ihn noch benötigen logge dich bitte einfach auf https://login.infra4future.de ein.
Falls nicht, musst du weiter nichts tun und wir werden deine Account in ca. 3 Monaten löschen.
Viele Grüße,
das Infra4Future Team
