+This code *is* PD. You (public) have all the rights to the code.  [But
+this also means you (singular) do not have any *extra* rights to the code,
+hence it is impossible for you to restrict the use and distribution of
+this code (original) in any way.]
+
+Dedication:
+
+This posting is a dedication to an old 750 that started out running 4.1BSD
+and had 1.5 meg, 1 dz11, and 2 Rk07 drives.  It was named yetti [sic] by
+accident, and was managed by the author until its retirement two years
+ago. [the name yetti now identifies a different machine]
+
+If you have any important fixes and/or speed improvements, I am much
+interested. I am also interested in hearing about any unique applica-
+tions of M4. I am NOT interested in gratuitous hacks or "neat"
+kitchen-sink features.
