> The daisy-backup-tool requires to have a -l LOCATION option passed to it in the args.
> If it is not set a nasty NPE is thrown:
> java.lang.NullPointerException
>         at java.io.File.<init>(File.java:194)
>         at org.outerj.daisy.backupTool.BackupTool.main(BackupTool.java:69)
> It would be better to check if the argument is set (I suppose commons cli has stuff for this) and switch to providing the -h output with some additional message if it is not.
