Wyvern is a command-line tool written in rust that is meant to make downloading GOG games and associated activities easier and faster on linux. It features:
Installing games without need for the graphical installers
One-command updating of games to their latest versions, while only updating files that have changed between versions.
GOG Connect functionality so you can scan for and claim games without leaving the terminal
Syncing save files to a filesystem backup(with integration with cloud services being worked on).
Optional(compile with the 'eidolonint' feature) integration with eidolon, so that it automatically registers installed games to eidolon.
The GitHub repo is a mirror of the main sr.ht repository.
