+promo_cleanup
+=============
+
+This script enumerates all subfolders under a folder named "Promotions" on
+your IMAP server and deletes everything more than a week old.  Use it
+against mailers who aren't exactly sending spam but that you don't want
+cluttering your main inbox by using something like procmail or sieve to sort
+them into Promotions subfolders.  This can be set to run as a daily cronjob
+to keep things from getting out of control.
+
+Configure with the following environment variables, which should be
+self-explanatory:
+
+```IMAP_SERVER```
+```IMAP_USER```
+```IMAP_PASSWD```
+
+The script assumes you have SSL enabled on port 993 on your IMAP server.  If
+you don't, you're doing it wrong.
