96 // when a script has auto_retire in it, it can be dropped into an
97 // object and the most recent version of the script will destroy
98 // all older versions.

102 // in the form "major.minor".

104 // number that increases with each newer version of the script. thus,
105 // "hazmap v0.1" might be the first script in the "hazmap" script continuum,
106 // and "hazmap v3.2" is a more recent version.
