+// auto-upgrader, by fred huffhines, distributed under GPL license. 
+//   partly based on the self-upgrading scripts from markov brodsky and jippen fadoul. 
+// the function auto_upgrade() should be added to a version numbered script that you wish 
+// to give the capability of self-upgrading.  see example invocation at end of file. 
+//   this script supports a notation for versions where a 'v' character and a number in the 
+// form "major.minor" reside at the end of script names, e.g. "grunkle script by ted v8.2". 
+// when the script is dropped into an object with a different version, the most recent 
+// version eats any existing one.
