==================================================================

Here is the GNU grep home page:
    http://gnu.org/s/grep/

For a summary of changes and contributors, see:
  http://git.sv.gnu.org/gitweb/?p=grep.git;a=shortlog;h=v2.18
or run this command from a git-cloned grep directory:
  git shortlog v2.17..v2.18

To summarize the -2 gnulib-related changes, run these commands
from a git-cloned grep directory:
  git checkout v2.18
  git submodule summary v2.17

Here are the compressed sources and a GPG detached signature[*]:
  http://ftp.gnu.org/gnu/grep/grep-2.18.tar.xz
  http://ftp.gnu.org/gnu/grep/grep-2.18.tar.xz.sig

Use a mirror for higher download bandwidth:
  http://ftpmirror.gnu.org/grep/grep-2.18.tar.xz
  http://ftpmirror.gnu.org/grep/grep-2.18.tar.xz.sig

[*] Use a .sig file to verify that the corresponding file (without the
.sig suffix) is intact.  First, be sure to download both the .sig file
and the corresponding tarball.  Then, run a command like this:

  gpg --verify grep-2.18.tar.xz.sig

If that command fails because you don't have the required public key,
then run this command to import it:

  gpg --keyserver keys.gnupg.net --recv-keys 7FD9FCCB000BEEEE

and rerun the 'gpg --verify' command.

This release was bootstrapped with the following tools:
  Autoconf 2.69.117-1717
  Automake 1.99a
  Gnulib v0.1-76-g497f4cd
