# Purpose {{{
## Try to centralize all game's save that respect XDG specifications in order to:
## easily backup all save
## easily restore it
## be able to access it from anywhere
## … all you can do with a Nextcloud (share, versionning,…)
##
## 1. Move save directories of a list of known games from XDG's
## directories to a remote directory (Nextcloud, remote mount,…).
## Then create a symlink in XDG directories to the remote game
## directory.
##
## 2. If a directory doesn't exist, check if a remote one is
## available and symlink it.
##
## KISS: Only manage save directories from Steam userdata. For other
## paths (Steam,…) check other scripts.
