-% WARNING! This is a heavy magic! If you want something more understandable,
-% you will have to write it yourself (if it is possible in a stack-oriented
-% language that PostScript is). There are some constants you can
-% change and see what happens, but I think the slurs should be almost
-% always satisfiable. When not, let me know at:
-% standa@hiero.cz
-% Also any bug reports and comments are welcomed.
