Hazel and MP3 Gain

Hello there.
So I am trying to automate my music collection. I have already got Hazel to rename my files and add them to my iTunes library.
What I would really like is to use MP3 gain (which I have just downloaded the command line version of) to also run.
Has anyone out there had any dealings with the command line version of this software? I use the GUI version and am happy with it but there doesn't seam to be a lot of documentation on it.
Cheers
