A static binary rewriter that does not use heuristics

I read the readme. I still don't know what is "rewriting" a binary or why one would want to do it. Can someone explain?

This is the paper referenced in the README: <a href="http:&#x2F;&#x2F;web.cse.ohio-state.edu&#x2F;~lin.3021&#x2F;file&#x2F;NDSS18a.pdf" rel="nofollow">http:&#x2F;&#x2F;web.cse.ohio-state.edu&#x2F;~lin.3021&#x2F;file&#x2F;NDSS18a.pdf</a>

Could this tool be used to produce eg a statically-linked version of `curl` that would work the same on any Linux, without needing to build curl from sources?

Is this for antivirus signature evasion? If so, wouldn&#x27;t it need to work on itself?
