60 // !! keep in mind that this code must be *copied* into another
61 // !! script that you wish to add auto-retirement capability to.
62 // when a script has auto_retire in it, it can be dropped into an
63 // object and the most recent version of the script will destroy
64 // all older versions.
66 // the version numbers are embedded into the script names themselves.
67 // the notation for versions uses a letter 'v', followed by two numbers
68 // in the form "major.minor".
69 // major and minor versions are implicitly considered as a floating point
70 // number that increases with each newer version of the script. thus,
71 // "hazmap v0.1" might be the first script in the "hazmap" script continuum,
72 // and "hazmap v3.2" is a more recent version.
