+// huffware script: altitudinator, by fred huffhines
+//
+// displays an altimeter reading in the object's text.
+// modified by fred huffhines, originally from LSL scripting library.
+//
+//   this script is licensed by the GPL v3 which is documented at: http://www.gnu.org/licenses/gpl.html

+// 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.
