                $this->cli_help['name'] = 'rte_images -- Looking up all occurencies of RTEmagic images in the database and check existence of parent and copy files on the file system plus report possibly lost files of this type.';
                $this->cli_help['description'] = trim('
Assumptions:
- a perfect integrity of the reference index table (always update the reference index table before using this tool!)
- that all RTEmagic image files in the database are registered with the soft reference parser "images"
- images found in deleted records are included (means that you might find lost RTEmagic images after flushing deleted records)

The assumptions are not requirements by the TYPO3 API but reflects the de facto implementation of most TYPO3 installations.
However, many custom fields using an RTE will probably not have the "images" soft reference parser registered and so the index will be incomplete and not listing all RTEmagic image files.
The consequence of this limitation is that you should be careful if you wish to delete lost RTEmagic images - they could be referenced from a field not parsed by the "images" soft reference parser!
Another limitation: In theory a RTEmagic image should be used from only one record, however TCEmain does not support this (unfortunately!) so when a record is copied or versioned no new version will be produced. This leads to a usage count of more than one for many RTEmagic images which is also shown in the overview. At this point in time its not considered a bug and there is no fix for it.

Automatic Repair of Errors:
- There is currently no automatic repair available

Manual repair suggestions:
- Missing files: Re-insert missing files or edit record where the reference is found.
- Lost files: Delete them if you do not recognize them as used somewhere the system does not know about.
