dir: /plugins/wavesurfer/README/
This directory contains a plugin file and a configuration file for wavesurfer. It's actually just a label widget with some added functions. Install them in ~/.wavesurfer/1.6/{plugins,configurations} or /usr/lib/wsurf1.6/{plugins,configurations} and they should appear next time you launch wavesurfer. The config box to set different options is still to be written.
