11 // huffware script: auto-retire, by fred huffhines, version 2.8.
12 // distributed under BSD-like license.
13 // !! keep in mind that this code must be *copied* into another
14 // !! script that you wish to add auto-retirement capability to.
15 // when a script has auto_retire in it, it can be dropped into an
16 // object and the most recent version of the script will destroy
17 // all older versions.
19 // the version numbers are embedded into the script names themselves.
20 // the notation for versions uses a letter 'v', followed by two numbers
21 // in the form "major.minor".
22 // major and minor versions are implicitly considered as a floating point
23 // number that increases with each newer version of the script. thus,
24 // "hazmap v0.1" might be the first script in the "hazmap" script continuum,
25 // and "hazmap v3.2" is a more recent version.
27 // example usage of the auto-retirement script:
30 // auto_retire(); // make sure newest addition is only version of script.
33 // this script is partly based on the self-upgrading scripts from markov brodsky
34 // and jippen faddoul.
