[plt-scheme] How does help desk work when you run from SVN?

Hi folks,

I just downloaded and built the trunk on Windows. When I hit F1 on a
name, the documentation seems to come up for the SVN build.The
information page here

http://svn.plt-scheme.org/

though, explains that one needs to download documentation separately.

Is this a holdover from pre-4.x days or does it still apply

Best wishes,

Grant
