Dear community,
EDIT: read the post by @jmiven just right below as it gives the actually correct information.
I just became aware that VSS has been archived and the repo has been renamed to reflect such change.
Maybe the Ada-Lang org could create a fork of the archived tools and allow for further community maintenance. After all, most of the tools created by AdaCore are open and we can further develop them if there is a will and action to do so.
Best regards,
Fer
