-// huffware script: auto-retire, by fred huffhines, version 2.5.
-// distributed under BSD-like license.
-// !! keep in mind that this code must be *copied* into another
-// !! script that you wish to add auto-retirement capability to.
-// when a script has auto_retire in it, it can be dropped into an
-// object and the most recent version of the script will destroy
-// all older versions.
-//
-// the version numbers are embedded into the script names themselves.
-// the notation for versions uses a letter 'v', followed by two numbers
-// in the form "major.minor".
-// major and minor versions are implicitly considered as a floating point
-// number that increases with each newer version of the script. thus,
-// "hazmap v0.1" might be the first script in the "hazmap" script continuum,
-// and "hazmap v3.2" is a more recent version.
-//
-// example usage of the auto-retirement script:
-// default {
-// state_entry() {
-// auto_retire(); // make sure newest addition is only version of script.
-// }
-// }
-// this script is partly based on the self-upgrading scripts from markov brodsky
-// and jippen faddoul.
