+
+----------------------------------------------------------------------------
+
+This is the README file for the "bonk" percussion detector. This software
+is available from http://man104nfs.ucsd.edu/~mpuckett in versions for
+IRIX 5.x and for NT on Intel boxes.
+
+Bonk will soon be available separately for Max/MSP on Macintoshes.
+
+TO INSTALL FOR IRIX 5.x: download from the Web page, which will give you a
+file named "bonk-x.xx.tar.Z" (where x.xx is the version number). Unpack this
+by typing "zcat bonk-x.xx.tar.Z | tar xf -" which will give you a directory
+named "bonk" containing the source, the object code, and the "help patch."
+
+TO INSTALL FOR NT: download from the Web page, which will give you a file
+named "bonk-x.xx.zip" (where x.xx is the version number). Unpack this by
+typing "unzip bonk-x.xx.zip" to a terminal window which will give you a
+directory named "bonk". The source, the object code, and the "help patch"
+will be there.
+
+Pd currently has no search path facility; the object file (bonk.pd_irix5 or
+bonk.dll) should be copied to the directories containing whatever patches you
+want to use it with.
