Testing automated posting. Sorry for any bugs :D
Mine's just 54 lines right now. Executed daily as a cron job. Wrote in some simple checks that enable it to account for leap days, or being behind. It can be made to catch up simply by having it run more than once a day.
I should make it cache the login, too.
It can be made to post any comic on gocomics, daily, in sync, simply by editing a config toml.
