# Purpose {{{
## Try to centralize all game's save 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 Steam's userdata,
## common or compatdata directories to a remote directory (Nextcloud, remote
## mount,…).
## Then create a symlink in userdata, common or compatdata Steam directory to
## the remote game directory.
##
## 2. If a directory doesn't exist, check if a remote one is
## available and symlink it.
##
## 3. List userdata subdirectories without symlinks.
##
## KISS : Only manage save directories from Steam's directories. For other
## paths ($XDG_DATA_HOME,…) check other scripts.

## Pattern of Steam saves in common to backup {{{
### Add the directory name of the game and the directory|file name to backup
### separated by a slash.
### To be able to manage white space in directory name, the field separator is %.
### eg. GAME NAME/data.save%other game/*.sav
### 620 − Portal 2 − https://pcgamingwiki.com/wiki/Portal_2 (solo only, multiplayer is on Steam cloud)
### 251470 − TowerFall Ascension − https://pcgamingwiki.com/wiki/TowerFall_Ascension (not managed cause no substree, check $XDG_DATA_HOME)
### 274190 − Broforce − https://pcgamingwiki.com/wiki/Broforce

# }}}
## Pattern of Steam saves in compatdata to backup {{{
### Compatdata contains directories for games using Steam play so it's too big
### to be fully moved to a remote storage.
### Add the game id and the directory|file name to backup separated by a slash.
### And, to be able to manage white space in pattern name, the field separator is %.
### eg. GAME_ID/savedata.xml%GAME_ID42/user.bin
