# wyvern ![](https://img.shields.io/crates/v/wyvern.svg?style=flat-square) [![builds.sr.ht status](https://builds.sr.ht/~nicohman/wyvern.svg)](https://builds.sr.ht/~nicohman/wyvern?)

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: 

- Downloading games

- 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](https://git.sr.ht/~nicohman/eidolon), so that it automatically registers installed games to eidolon.

The GitHub repo is a mirror of the main [sr.ht](https://git.sr.ht/~nicohman/wyvern) repository.
