Hi,

https://boostorg.github.io/build/manual/develop/index.html#bbv2.tutorial.libs
section presents this snippet:

project
   : requirements <library>/boost/filesystem//fs
   ;

Where does the fs target come from?

I tried to refer to that in Boost.GIL, but getting
   error: Unable to find file or target named
   error:     '/boost/filesystem//fs'

while /boost/filesystem//boost_filesystem works.

Is the docs outdated here?
