-// huffware script: huff-update server, by fred huffhines.
-//
-// this script is the server side of the update process. it should reside in an object that
-// has all the newest versions of scripts and objects that will be updated. when rezzed, and
-// at periodic intervals, it announces on a private chat channel that updates are available.
-// when objects respond that they might like an update, it tells them the scripts that it has
-// stored inside of it. if any of those scripts are an older version inside the client
-// (update requesting) object, then the client will request the newer versions. the server
-// object will stuff them into it and tell them to start running.
-//
-// this script is licensed by the GPL v3 which is documented at: http://www.gnu.org/licenses/gpl.html
-// do not use it in objects without fully realizing you are implicitly accepting that license.
