How to use Variety under KDE

To use Variety under KDE, after you install Variety and run it for the first time, please manually change your desktop wallpaper to ~/.config/variety/wallpaper-kde.jpg and keep it that way.

KDE support is harder than the other desktop environments because KDE provides no way to set the desktop wallpaper from the command line, without depending on KDE-specific libraries. So instead of this, Variety simply updates the file mentioned above and KDE itself updates the wallpaper when this happens.

UPDATE: Since KDE 4.11 the above method no longer works and there is now no way to make Variety automatically change the wallpaper under KDE.
