This script is used to import data from the plaintext backend used by the Clickthrough Tracking (any version of Dada Mail) extension or the Tracker plugin to the SQL backend.
Docs on how to move from the default backend of Dada Mail to one of the SQL backends is covered in length here:
http://dadamailproject.com/d/FAQ-default_2_SQL_backend.pod.html
This script should be run once you have moved over your backend from the Default to the SQL backend, NOT before.
You may also use this script, even though you have always run the SQL backend, since the Clickthrough Tracking extension always kept its logs in PlainText format. The Clickthrough Tracking extension was superceded by the Tracker plugin in v4.5.0 of Dada Mail.
