+// huffware script: welcomebot visitor list, by fred huffhines
+//
+// originally based on LSL wiki examples.
+// how to use this script:
+// 1) create an object that you want to track visitors to your area.
+// 2) change the parameters below to reflect your own information.
+// 3) add the script to your tracker object.
+// 4) reply to the script's rez email with the following commands:
+// list: send the current visitor list.
+// scan: scan the area near the greeter object.
+// clear: throw out the visitor list. sends a copy before deleting.
+//
+// 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.
+//
+
+//todo:
+// how do we reconcile having a config notecard with the giveaway ones?
+// just name it special?
+// we want the script not to reset when the parameters change!
+// it should just reset the notecard stuff and other variables.
+// no new setup on email and all that stuff!
+// maintain list of last visit times.
+// just as a string?
+
+
+// put your e-mail address here.

+// when a script has auto_retire in it, it can be dropped into an

+// all older versions.
+//
+// the version numbers are embedded into the script names themselves.
+// the notation for versions uses a letter 'v', followed by two numbers
+// in the form "major.minor".
+// major and minor versions are implicitly considered as a floating point
+// number that increases with each newer version of the script. thus,
+// "hazmap v0.1" might be the first script in the "hazmap" script continuum,
+// and "hazmap v3.2" is a more recent version.
+//
+// example usage of the auto-retirement script:
+// default {
+// state_entry() {
+// auto_retire(); // make sure newest addition is only version of script.
+// }
