My customized shell script isn't as robust as it should be and I don't want to reinvent an inferior version of what must surely already exist.What tools would you recommend for managing dotfiles that are robust, doesn't have external dependencies, uses git and are idempotent?I'd like something that manages directories of files (e.g. ~/.vim/ftplugin/) in sub-directories, as well as in $HOME. If the tool can deal with multiple systems (MacOS, CentOS, debian) then even better!Thanks!
