I have no idea who wrote that thing, sorry.

How is adding this file anywhere going to help?  Coverity is a closed
source tool that a few of us are "lucky" to be able to use, and even
then, it's tightly restricted what we can do with it.  The only real
users that this could benefit is anyone who is paying for the tool, and
if they are doing that, they are not allowed to share the results of the
output with anyone else (as per the license of the tool).  So unless you
are going to be doing this work on your own, with a paid copy of the
tool, who will use it?
