In my MD fold i see a Liveries notepad file and it looks like this

MDG,McDonnell Douglas,MADDOG,0,0,0,0,1,1,1,0,0,0,0
AAL,American,N494AA,0,1,1,0,0,1,1,0,0,0,0
LAV,Aeropostal,N905TA,0,1,1,0,0,1,1,0,0,0,0

Can you pleas tell me what each of the 0 & 1's represent. Im guessing it has to do with the LM setup page, but not sure and would like to know. Also how can i install just the "American" line and nothing else?
Thanks
