This is an extremely special-case utility, and I don't even use it any more.

At the time, I was running ejabberd on my server so people could contact me via XMPP federation, and this script would read the MySQL database for the data ejabberd stored for JEP-0136 support, and break that data up appropriately into Maildir files.

In laymen's terms: it took my Google Talk chat logs and archived them to a mail folder.

This was a really handy thing that would run in a cronjob and try to keep individual units of conversation split into separate emails, but to be clear, I don't host an XMPP server any more--everyone I talked with moved on to other services, like iMessage and later, Slack and Discord...and I don't know if the database schema has changed since, etc, so use at your own risk.

Still, this was useful at one time, so I'm leaving it here in case it is useful again.
