Lion Disk Maker (http://blog.gete.net/lion-diskmaker-us/) is a new, small application programmed with AppleScript that you can use with Mac OS X 10.6 or 10.7 to burn a DVD or build a bootable USB key from Mac OS X Lion’s Installation program.

As soon as you launch the application, it checks the presence of X Lion Install in the /Applications folder, or tries to find one using Spotlight. Then, it proposes to build a DVD or create  bootable install disk. USB and FireWire drives are supported, as well as SD-Cards.

To burn the DVD, you’ll need a SuperDrive and a writable DVD (single layer, 4,7 GB). To build a bootable disk, you’ll need a 4GB (minimum) USB or Firewire drive or an SD-Card. Lion DiskMaker is free, but donations are gladly accepted by its developers.
