GNOME.org: Metatheme 0.5.0 releasedNov 25, 2000, 00:29 (0 Talkback[s])
"Metatheme alpha release 0.5.0 (code-named "Ogling Octopus") has been released. This represents the first preview release of the gnome meta-themeing system. I'd like to personally thank Helix Code for sponsoring metatheme development this summer."
"Metatheme provides a way for users to save and restore snapshots of their system's current theme configuration. This allows one-click simultaneous changing of background image, Gtk+ theme, Sawfish window manager theme, and so forth."
