This directory should contain only patches from the stable branch of 
TeXLive 2012 <http://tug.org/svn/texlive/branches/branch2012>

Thanks to Karl Berry and the other TeXLive contributors for agreeing
to maintain this and for linking it at http://tug.org/texlive/distro.html

From an svn checkout, something like this will generate patches:
  svn diff -r from#####:to##### > patchname
