This app was reinitialized in December 2021. A lot of scripts became outdated and a new strategy for the mirroring operations was chosen. Basically the new approach brought some kind of simplification. Three may be listed below:

1. a node self-reference field (child to parent) was discontinued;;
2. the "logical" primary key became name and parentpath;
3. the approach to finding repeats (based on sha1) was simplified to a db-SELECT.

The next challenge is to add some sort of GUI to help use the app without the command line.
