21 // distributed under BSD-like license.
22 // !! keep in mind that this code must be *copied* into another
23 // !! script that you wish to add auto-retirement capability to.
24 // when a script has auto_retire in it, it can be dropped into an
25 // object and the most recent version of the script will destroy
26 // all older versions.
28 // the version numbers are embedded into the script names themselves.
29 // the notation for versions uses a letter 'v', followed by two numbers
30 // in the form "major.minor".
31 // major and minor versions are implicitly considered as a floating point
32 // number that increases with each newer version of the script. thus,
33 // "hazmap v0.1" might be the first script in the "hazmap" script continuum,
34 // and "hazmap v3.2" is a more recent version.
36 // example usage of the auto-retirement script:
39 // auto_retire(); // make sure newest addition is only version of script.

43 // and jippen faddoul.
