SCript to send a Heartbeat signal to the Teleport Database.

Version: 1.0.0

Date: 01 January 2025

Author: River Drifter @ little-sense.au:9000 \email river.nosp@m._dri.nosp@m.fter@.nosp@m.auss.nosp@m.iebro.nosp@m.adba.nosp@m.nd.co.nosp@m.m.au

Theis script takes a list of projects and a hyperlink to documentation and displays a table on the face of an object. If a cell of the table is touched, the script will attempt to open the hyperlink in a browser.

NOTE: The file extension ".osl" indicates the script uses the Open Simulator Script language (OSSL) and will not function in the Second Life environment. If the script will function using just the Linden Scripting Language (LSL), it will have a a file extension of ".lsl".
