[CQ-Contest] Contest scoring software

[Chuck Gooden]

I am curious what software is used to analyze the cabrillo files and 
officially score the contest results.  I am not requesting information 
on contest logging software like N1MM that hams used to create the files 
they submit after a contest.  But rather the software the contest 
organizers use to score and come up with the official scores.

Is this software propitiatory or open source?  Available on a Github?
