There's a list of features here, but it isn't complete.
http://www.boost.org/boost-build2/doc/html/bbv2/advanced/builtins/features.html
If you really want to look at the source, most features are defined
in tools/builtin.jam

You can link to a boost library using
/boost//iostreams (e.g.) if you have
use-project boost : path/to/boost ;
somewhere.  It doesn't have to be in Jamroot.
It can be in one of the configuration files.
