Just plain OSX buttons to be used with your openbox theme. This is not a complete theme. There are just button icons and buttons color theming for windows buttons to be used with any openbox theme of your own choice.
- paste these button icons in your openbox-3 theme folder (i.e. overwrite the old ones),
- open the buttons_theming.txt file in your text editor and copy and paste it into the end of your themerc file in your openbox-3 theme folder.
