# Description: Program to create a recovery USB flash drive directly from the machine by Clonezilla live.
# To use it:
# Prepare:
# (1) A bootable Clonezilla live, either on CD or USB flash drive (master one)
# (2) A USB flash drive with 1 FAT/EXT/BTRFS/NTFS partition (USB flash drive B)
# Then
# (1) Insert master one and USB flash drive B on the machine which you want to take the image
# (2) Boot Clonezilla live with master one. Do not choose TORAM mode. Use normal mode
# (3) Run this program. Without any option it will enter interactive mode. You can also use some options. Run with option "-h" for more info.
# Then it will take the hard drive (say /dev/sda) as an image, put the image on USB flash drive B (e.g. /dev/sdb1), make it bootable. Then you will have a recovery USB flash drive. All is done in this program.
# //NOTE// The boot loader of destination device (USB flash drive B) will be overwritten. USE IT CAREFULLY!!!
