How to build eMMC flasher image, ubuntu 13.04

Hi All, I am running http://rcn-ee.net/deb/rootfs/raring/ubuntu-13.04-console-armhf-2013-05-29.tar.xz from microSD, have done some customizations and installed new packages and would like to build a flasher image for the eMMC. How do I do that easily?

Thanks

So with my image the tool is under:

:~$ cd /boot/uboot/tools/
:/boot/uboot/tools$ sudo ./update.sh
:/boot/uboot/tools$ cd scripts/
:/boot/uboot/tools/scripts$ sudo ./beaglebone-black-copy-microSD-to-eMMC.sh

After about 5-10 minutes the microSD will be transferred to the eMMC..

Regards,

Awesome, I heard about your magic scripts and that worked flawlessly and easily!!
Is there a way to create a flasher image though, the one you boot off of and press and hold the boot switch to program the eMMC automatically without any manual intervention?
