83 // object and the most recent version of the script will destroy

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

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