This program allows you to preview and switch GTK1 themes. Please
note, that this will list all GTK themes, as well as any XFCE window
manager themes. So don't get confused by the long list and make sure
the theme you select _is_ for GTK1.
If you are looking for an easy to install GTK1 engine and theme,
check the gtk1-industrial-engine, available from SlackBuilds.org.
