+k_jack~ - General signal in/out external for pure data. Kjetil S. Matheussen.
+V0.0.2
+
+
+This external makes objects with signal inlets and outlets to jack ports. See
+the help patch.
+
+It works by calling functions and using variables in pd/src/s_audio.c that probably
+was not ment to be used for this purpose. But it works. And thats whats important.
