// 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.
