/* !TODO!: This would require the install.php to make a note of all the actions that were skipped and/or performed */
/* !TODO!: Might be a good idea to create a backup of the database before removing anything */
// !TODO!: -TODO-: I remove only that which is related to the Manager, it is in my opinion not a critical configuration information. This information is partially present in other files.
