-// huffware script: auto-retire, by fred huffhines, version 1.9.
-// distributed under BSD-like license.
-// partly based on the self-upgrading scripts from markov brodsky and jippen faddoul.
-// the function auto_retire() should be added *inside* a version numbered script that
-// you wish to give the capability of self-upgrading.
-// this script supports a notation for versions embedded in script names where a 'v'
-// is followed by a number in the form "major.minor", e.g. "grunkle script by ted v8.2".
-// when the containing script is dropped into an object with a different version, the
-// most recent version eats any existing ones.
-// keep in mind that this code must be *copied* into your script you wish to add
-// auto-retirement capability to.
-//
-// example usage of the auto-retirement script:
-//
-// default {
-// state_entry() {
-// auto_retire(); // make sure newest addition is only version of script.
-// }
-// }
