This question has to do both with RPA and with iowa.

I have recently installed iowa via RPA as suggested on the iowa web
site (on this page: http://enigo.com/projects/iowa/index.html).

Now, I'm going through the iowa tutorial, but I can't find the WEBrick
example.  The tutorial says to do the following:

  cd examples/webrick/iowa
  ruby webrick_iowa.rb

However, I don't have a clue as to where RPA put the
"examples/webrick/iowa" directory, or for that matter, if it even
installed that directory at all.

Can anyone point me to where that directory lives when iowa is installed
via RPA?

If that directory doesn't exist, I know that I can get it by downloading
and unpacking the iowa tarball from SourceForge.  However, that obviates
the need to use RPA in the first place.

And if indeed SourceForge is a better choice for iowa downloads, what
will happen from now on if I give up on RPA?  In using it for this iowa
download, it created a package tree that contains the installations of
iowa and all its dependencies, some of which are upgrades of packages
that I had previously installed outside of RPA.  If I stop using RPA,
will I have to remove the RPA package tree in order to keep my installs
in sync?  If so, will I have to re-install everything that RPA has
recently put under its tree?

Thanks in advance for any insights you might be able to offer about all
of this.
