+NAME
+       burn.sh - CD/DVD burning frontend
+SYNOPSIS
+       burn.sh [-n <diskname>] path [path [path [...]]]
+DESCRIPTION
+       burn.sh is a frontend to mkisofs, cdrecord and growisofs. It accepts
+       multiple files and directories as arguments which should be burned
+       to a CD or DVD. burn.sh does some filesystem limitation checks and
+       decides on its own if a CD or a DVD is created.
+OPTIONS
+       -s
+             Call the burning process in simulation mode
+       -n <diskname>
+             Specifies the Joliet name for the new disk if none is given
+             the current date is used
