Subject: Added about 64 files that I hadn't realized weren't in the CVS
 repository.  Threw in pd/portaudio/pa_win_wdmks for good measure, although I
 haven't tried compiling that in yet (no windoze machine handy today).

+#X text 26 129 The two controls specify \, first \, the center frequency
+\, and second \, the sharpness of the filter \, commonly called "q".
+If you increase q to 10 or 20 \, you will see a drop in total signal
+power \, and moreover \, you'll see and hear the resonant frequency
+more clearly in the result.;
+#X text 28 30 A simple resonant band-pass filter is provided in the
+bp~ object. Resonant filters can be tuned to a specific "center frequency"
+and then will pass that frequency while attenuating other frequencies
+(the further from the center frequency \, the more attenuation). This
+patch uses a white noise source to demonstrate bp~.;
