Yes.  Steven is referring to the source *tree*, i.e. the files of Boost
laid out exactly as they come out of SVN.  Usually this comes from an
SVN working copy or a tarball.  Install generally creates a copies the
headers, built binaries, docs, etc. into standard system locations so
that you can write code dependent on Boost without actually having a
complete checkout of the Boost source.
