+
+GNU xorriso comes with a script named 
+  xorriso-dd-target/xorriso-dd-target
+which uses the util-linux program lsblk to find suitable hard-disk-like
+target devices for copying hard-disk bootable ISO images onto them. Such images
+are offered by GNU/Linux distributions for installing their system.
+
+xorriso-dd-target gets installed only if ./configure detects to run on a
+GNU/Linux system. It refuses to start on non-Linux kernels or if program lsblk
+is not found in /usr/sbin, /sbin, /usr/bin, /bin.
+
+For introduction, examples, and details see in the build directory
+  man xorriso-dd-target/xorriso-dd-target.1
+  info xorriso-dd-target/xorriso-dd-target.info
