+Medusa, the asynchronous communications framework upon which
+supervisor's server and client code is based, was created by Sam
+Rushing:
+
+  Medusa was once distributed under a 'free for non-commercial use'
+  license, but in May of 2000 Sam Rushing changed the license to be
+  identical to the standard Python license at the time.  The standard
+  Python license has always applied to the core components of Medusa,
+  this change just frees up the rest of the system, including the http
+  server, ftp server, utilities, etc.  Medusa is therefore under the
+  following license:
