+                         Can be specified multiple times.
+     -s URI              Generate a small ISO file which downloads the squashfs
+                         file from the specified URI. Please note that due to
+                         restrictions in the bootprocess only IPs are allowed.
+                         Supported protocols are: http and ftp
+
+     Examples:
+     $0 -s http://192.168.23.42:8000/grml/ -o small.iso grml64_2010.12.iso
+
+     Will generate a file small.iso which tries to download the squashfs file from
+     http://192.168.23.42:8000/grml/ - the squashfs file is placed in the same
+     output directory as the ISO file.
