+diskimg: write disk images
+
+Usage:
+	diskimg [-a algo] [-v] image device
+
+Flags:
+	-a algo		Select the hashing algorithm to use. The default
+			is 'sha256'. Specifying an algorithm of 'list'
+			will print the supported algorithms to standard
+			output and exit with error code 2.
+	-v		Enable verbose (debug) output.
+
+Examples:
+	
+	Copying images/server.img to /dev/sda:
+
+	$ sudo diskimg images/server.img /dev/sda
+
+	Write a bladerunner node image to /dev/sda:
+
+	$ sudo diskimg -v ~/code/bladerunner/packer/build/cm4-cnode-ubuntu-22.04.2.img /dev/sda
+	opening image /home/kyle/code/bladerunner/packer/build/cm4-cnode-ubuntu-22.04.2.img for read
