I wouldn't use it. My OS already comes with deamonizing functionality and I'd very much prefer for my daemons to all work similar.
You'd actually have to write code to use it which means you have to do (possibly a lot) of work to deamonize an existing program. I'd expect a deamonizer to take command line arguments.
Configuration requires code hacking. It's not using a config file.
Very big no no: it has its own idea where logging should go to. Not making use of the syslog functionality doesn't make me give it any high marks.
