			=What the parts do=

			This shall be a very brief explanation on what the components provided by OSE (so excluding octopi, freecad, apache, python) do.

			==The scripts Folder==

			In this Folder we have the heart of the recognition software for the 3d printers, namely the Scanner.py
			These a bit under 200 Codelines have two main purposes:

			Checking the device folder for any kind of Serial connection, then sending a basic GCode to get information and verify that it is indeed a printer

			Writing all the devices down and adjust several files on the system according to it


			This scripts also removes files it has produced when it is started so it can start from the basics. The data this script collects is also saved here so it can be accessed from the other programs. Everything else stored here are basic blueprints of the files this script creates.

			This however does not mean this script alone can do the job, this Script has to be run as root and after its running there are several ownership shifts to be done for the new setup to function. These commands are located in the

			==rc.local==

			This script will be run on linux startup and trigger, if the Scanactive.txt is set, the Scanner and after it the modifications necessary to make the new files function. After all that, a reboot is necessary, so the file does that as well.

			==RebLabHUB==

			This is basically the Webserver, so it contains the HTML, css, js and as a core the __init__.py, which sets all the parts together with pythons flask. The Script reads the data provided by the Scanner and adjusts itself accordingly within the html code. This file will actually be rewritten every time the scanner is run, there will be a few lines added at the end of the file. This may seem a strange approach, but it seems to be impossible to name a recursive amount of pages with flask, so it seemed the best workaround and lastly, it works flawless.

			The Scanactive.txt is within this folder, so the webserver can trigger this rather complex event of the scan with root rights without further access violation.

			The conf file named the same way is of course the apache conf file, and it's most minimalistic with it's setup of flask
