There is a new pretest available in
<ftp://alpha.gnu.org/gnu/emacs/pretest/emacs-$NEW.tar.gz>
Please report results from compiling and running the pretest to
<bug-gnu-emacs@gnu.org>. Your feedback is necessary for us
to know on which platforms the pretest has been tried.
If you have the tars from the previous pretest, and you have the
\`xdelta' utility, you can instead download the much smaller
<ftp://alpha.gnu.org/gnu/emacs/pretest/emacs-$OLD-$NEW.xdelta>
You can use a command like
$ xdelta patch XDELTA PREVIOUS-TAR CURRENT-TAR
to generate the new tar from the old one, where XDELTA is the xdelta
file you downloaded, PREVIOUS-TAR is the tar file from the previous
pretest, and CURRENT-TAR is the name of the tar file you downloaded.
Information about xdelta can be found on the GNU ftp site, in
/non-gnu/xdelta.README.
