Note: This whole script uses UPnP-PortMapper by christoph at sourceforge.net. Go check it out, it's what this script uses to open port 25565. I have been given permission from him to use it in this script. Automatic Server with no port forwarding requiredThis script isn't designed to be all fancy-pancy with a GUI and everything, just a CLI, and easy to use.It's simple to use, everything is automatic. Just download CraftBukkit, open "Start Server.bat", and it does everything. You don't need to type any configuration options (unless you want to) or do anything. It will find your internal IP itself, open port 25565 and start the server. Literally, you just double click the script and boom. Everything's done. Unless there's an issue, but you can get help for those on here (so far there are none on my end, woo!)DownloadOnce you've downloaded the zip file, just extract it to a folder of your choice, and download craftbukkit, rename the craftbukkit jarfile to "craftbukkit.jar" without quotes and open "Run Server.bat".Download here PGP SignatureConfiguration file (settings.bat) and how to use itThe script comes with, and reads at startup, a configuration file called settings.bat.
