does enable-beagle-flasher create a compressed image?

If enable-beagle-flasher ran on the eMMC makes the SD image a flasher but does not create a compressed image I can send to a customer, what is the best way to compress the image into a flasher.img.xz file?

Dd the microsd

Wow, I go round and around trying to figure out the ins and outs of the BBB but I forget some of what I learned earlier. When you said use the dd command I remembered seeing that in the BeagleBone Cookbook. Thanks again!
