+filterstamp.sh is a script to copy a filter and change filenames and all
+occurrences of the old name to the new name.
+
+This is used for writing new audio filters. The best one to copy for now is
+passthrough; it works on raw/audio int or float data.
+
+If your new filter is called StereoPan, for example, then do this :
+
+cd gst
+../tools/filterstamp.sh Passthrough StereoPan
+cd stereopan
+make
+
+(Please note the upper- and lower-case !)
+
+You should also add a line to configure.ac to make sure the Makefiles are built
+correctly. Just search for "passthrough" and add corresponding "stereopan" (or
+whatever your plugin is) lines.
+
+Register it, then try it out. It shouldn't do anything !
+
+Now edit the filter.func in the new directory; this file contains the body
+of the main processing loop.
