Since the inclusion of svnlite in base, there is no longer a need to install the subversion port or package to rebuild the OS. Throughout Chap 23, starting with the Synopsis at 23.1 and the Note which says to first install subversion, reference is made to svn, no mention of svnlite.
The documentation is still broken by using the "svn" command instead of "svnlite". Novice users won't understand why the commands aren't working.
