Command wrapping: The wrap command runs an external command between mod activation and deactivation.
Configuration: Game configurations use TOML and are placed in $XDGCONFIGHOME/mod-manager.
Deployment method: virtual
How it works: It mounts game files in place with configured modifications layered on top, then unmounts the overlay and restores the original files after the session.
Installation: The README gives source build instructions using Rust and Make or Cargo, followed by installation with make install.
Intended use: The README demonstrates applying modifications to a Steam game by adding a mod-manager wrap command to the game's startup parameters.
Known limitation: The README warns users not to change original game files or mod files while they are mounted because OverlayFS behavior is undefined.
Launcher compatibility: The on-demand file replacement is described as transparent to launchers such as Steam.
