wlib.wrapperModules
wrapper modules are modules which set config.package and define convenience options for wrapping that package with a configuration.
They are specific to that program, and make configuring programs in an ad-hoc way stress-free!
They include shortlist options for common configuration settings, and/or for providing a config file to use.
wlib.wrapperModules contains paths to these wrapper modules.
The flake also exports wrapper modules that have been partially evaluated for convenience.
This allows you to do something like inputs.nix-wrapper-modules.wrapperModules.tmux.wrap { inherit pkgs; prefix = "C-Space"; }, to build a package with a particular configuration quickly!
You can then export that package, and somebody else could call .wrap on it as well to change it again!
