# 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 XDG. For other paths (Steam, home,…)
## check other scripts.
