The EmailSummary plugin sends an email summary of the inbox to users in the
network.

After enabling the plugin, users will have an option to enable/disable the
feature in their "Email Settings" section.

You can run ./script/sendemailsummary.php to send emails (options are
documented in the file). You can run this script automatically via your OS's
cron mechanism to send emails regularly.
