// 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.
// }
// }
