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