	make release		make release

			After make release has finished there will be a directory on the same level as your top level project directory called:

			myproject.released

			Inside of that folder there will be a folder with the current date. Go to the most recent directory and there will be a file called cae_fpga.tgz, this file needs to be copied into the directory:

			/myprojectname/personalities/<personality number>/

			Example command:

			cp cae_fpga.tgz ../../myprojectname/personalities/<personality number>/ae_fpga.tgz

			Note that cae_fpga.tgz needs to be renamed to ae_fpga.tgz

			Note that make and make release will NOT do this copy for you. If you forget you will still be using the old personality
