Message:
  • @everyone: Do not create a branch until I've added the svn:eol-style property correctly. Otherwise this would cost me another 4 hours or so when we want to merge back.
  • merged network branch back to trunk
  • I had to omit the changes from last evening concerning the line endings
  • might not work yet because of the line endings
  • @beni: script branch is the only branch still open. you probably will have to apply a patch because of inconsistent new lines
