A dotfile manager in this context is a way to transfer them between machines, not to edit them. As long as you're able to sync the folder containing the dotfiles (through Dropbox or Git or a thumb drive), you can use this program to install/uninstall your dotfiles on whatever machine you're using. It allows you to keep non-centralized files in a centralized location with very little setup, basically. My window manager config lives in several different directories around my home folder, but with this I just set a mapping from repo locations to the home directory and everything is handled automatically.
