Sway, the i3-compatible tiling Wayland compositor. You can manually launch
Sway by executing "exec sway" on a TTY. Copy /etc/sway/config to
~/.config/sway/config to modify the default configuration. See

"man 5 sway" for more information'';

If the package is not overridable with `extraSessionCommands`, `extraOptions`,
`withBaseWrapper`, `withGtkWrapper`, `enableXWayland` and `isNixOS`,
then the module options {option}`wrapperFeatures`, {option}`extraSessionCommands`,
{option}`extraOptions` and {option}`xwayland` will have no effect.
Set to `null` to not add any Sway package to your path.
This should be done if you want to use the Home Manager Sway module to install Sway.
