KDE Launcher is an AppleScript Studio application that starts a Fink install of KDE with functional settings that actually work for OS X without changing all X11's configurations so it works poorly for everything else. It also runs KDE in a separate and distinct instance of X11 allowing the user to run KDE in an optimized environment using its window manager and with its own Dock icon, while simultaneously running other X11 applications in their regular Apple X11 using Apple's quartz-wm for its Aqua look and feel and better speed.
KDE Launcher is not KDE or X11. It is only a configuration and startup utility for them so in order to run it needs to have those already installed. I use Apple's X11 and Fink so that is what I created this to work with.
