Streamtuner2 is based on concepts and the UI of the original streamtuner 0.99.99 by Jean-Yves Lefort.

• The original was implemented in C with Gtk2 bindings, but already had the ability to harbour Python-based plugins.¹
• It was much faster and less memory-hungry.
• Keeping the parsing up to date with the ever-changing directory services however wasn't feasible.
• It still works with the Xiph/ICEcast directory, btw. Because their yp.xml didn't change so far.

The ST2 Google plugin was based on parsing rules from ST1. (It has been retired meanwhile though.)

¹ IIRC, I've originally even tried to reuse the original Python plugins. But that didn't pan out.
