Best way to collect 3rd Party Licenses from Boost Build?

[ncook-hxgn]

Hi,

I build boost and pack it up as nuget packages for our business unit to use. I would like to include third party licenses where appropriate, if applicable (is everything in boost licensed under BSL 1.0?).

I am currently using --stage some/path during my build, as this makes it easier to package up. It would be wonderful if --stage collated all the licenses under some/path for me too.
