43 // huffware script: auto-retire, by fred huffhines, version 2.4.
44 // distributed under BSD-like license.
45 // partly based on the self-upgrading scripts from markov brodsky and jippen faddoul.
46 // the function auto_retire() should be added *inside* a version numbered script that
47 // you wish to give the capability of self-upgrading.
48 // this script supports a notation for versions embedded in script names where a 'v'
49 // is followed by a number in the form "major.minor", e.g. "grunkle script by ted v8.2".
50 // when the containing script is dropped into an object with a different version, the
51 // most recent version eats any existing ones.
52 // keep in mind that this code must be *copied* into your script you wish to add
53 // auto-retirement capability to.

57 // auto_retire(); // make sure newest addition is only version of script.
