+// huffware script: auto-retire, by fred huffhines, version 2.8.
+// 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.
