[R] Wikis etc.

[Seth Falcon]

Regarding systems for presenting documentation and allowing user
comments, I recently came across Commentary (see homepage
http://pythonpaste.org/commentary/).

Haven't used it, but my impression is that comments and the main doc
are both stored in svn (and auto-committed for comment changes).  This
might help solve the problem of updating the doc upon a new R release
because you could take advantage of svn merge.

Of course, svn merge won't know whether the comments are still
appropriate or not :-(

Nevermind.
