  33 There is a new pretest available in
  34
  35   <ftp://alpha.gnu.org/gnu/emacs/pretest/emacs-$NEW.tar.gz>
  36   <ftp://alpha.gnu.org/gnu/emacs/pretest/leim-$NEW.tar.gz>
  37
  38 Please report results from compiling and running the pretest to
  39 <emacs-pretest-bug@gnu.org>.  Your feedback is necessary for us
  40 to know on which platforms the pretest has been tried.
  41
  42 If you have the tars from the previous pretest, and you have the
  43 \`xdelta' utility, you can instead download the much smaller
  44
  45   <ftp://alpha.gnu.org/gnu/emacs/pretest/emacs-$OLD-$NEW.xdelta>
  46   <ftp://alpha.gnu.org/gnu/emacs/pretest/leim-$OLD-$NEW.xdelta>
  47
  48 You can use a command like
  49
  50   $ xdelta patch XDELTA PREVIOUS-TAR CURRENT-TAR
  51
  52 to generate the new tar from the old one, where XDELTA is the xdelta
  53 file you downloaded, PREVIOUS-TAR is the tar file from the previous
  54 pretest, and CURRENT-TAR is the name of the tar file you downloaded.
  55
  56 Information about xdelta can be found on the GNU ftp site, in
  57 /non-gnu/xdelta.README.
