Conference Material page update

[Emmanuel Lécharny <el...@symas.com>]

Hi guys,


I have updated the
http://directory.staging.apache.org/conference-materials.html page,
pointing to the documents for each tak (at least, those I was able to
retrieve...)


Please take a few minutes to check that everything is fine for your
presentations, and please add the one you have provided in the few last
years, if they are not listed there !


Thanks !
