+ix::gui		http://whats-your.name/pd/gui/
+                http://suita.chopin.edu.pl/~czaja/miXed/externs/toxy.html
+
+hi, these objects were created in hopes of making the pd gui 'suck less'
+
+you need ToXY to use them: 
+cvs -d :pserver:anonymous@cvs.sf.net:/cvsroot/pure-data co externals/miXed
+cd externals/miXed && make && mv bin/* /usr/lib/pd/extra
+
+and loads of tk libraries, most are in portage, or try this:
+cvs -d :pserver:anonymous@cvs.sf.net:/cvsroot/blt
+cd blt && ./configure && make && make install
+
+
+to use a file called 'crack.wid' youd make an object [widget crack rock1] where 
+you pick an id..
+
+.,,
+
+misc notes (april 2005):
+tk is ugly without Cairo graphics (linux only), apply the patch, then 
+./configure --enable-xft --enable-cairo
+
+tkdnd is broken on linux with tk 8.5, unless you patch tkEvent.c
