-// huffware script: searchbert armature, by fred huffhines
-//
-// this script serves two useful functions for searchbert:
-// 1) this is searchbert's ease-of-use auto-repair feature. the script puts searchbert's arms back
-// on if they should ever get ripped off. this happens more frequently than one might expect, but this
-// script makes searchbert feel all better again.
-// 2) this script also manages the exchange of resources between the root prim and the arms. if there
-// are updates to the search pointer script or others, they'll get synched on a periodic basis.
-//
-// this script is licensed by the GPL v3 which is documented at: http://www.gnu.org/licenses/gpl.html

-// and "hazmap v3.2" is a more recent version.
