Is the source for the viewer available in colladadom 2.3.1

I recently downloaded collada_dom-2.3.1-src.tgz. The Readme.txt lists
out the directory structure. But when I uncompress the file it seems to
missing the folders fx, rt and and viewer. Are these available from
somewhere else?


I was able to find another file collada-dom-2.3.tgz that contained everything.
