+
+This is GNU grep, the "fastest grep in the west" (we hope). All
+bugs reported in previous releases have been fixed. Many exciting new
+bugs have probably been introduced in this revision.
+
+GNU grep is provided "as is" with no warranty. The exact terms
+under which you may use and (re)distribute this program are detailed
+in the GNU General Public License, in the file COPYING.
+
+GNU grep is based on a fast lazy-state deterministic matcher (about
+twice as fast as stock Unix egrep) hybridized with a Boyer-Moore-Gosper
+search for a fixed string that eliminates impossible text from being
+considered by the full regexp matcher without necessarily having to
+look at every character. The result is typically many times faster
+than Unix grep or egrep. (Regular expressions containing back-references
+will run more slowly, however.)
+
+See the files AUTHORS and THANKS for a list of authors and other contributors.
+
+See the file INSTALL for compilation and installation instructions.
+If there is no INSTALL file, this copy of the source code is intended
+for expert hackers; please see the file README-hacking.
+
+See the file NEWS for a description of major changes in this release.
+
+See the file TODO for ideas on how you could help us improve grep.
+
+See the file README-alpha for information on grep development and the CVS
+ repository.
+
+Send bug reports to bug-grep@gnu.org.
+
+KNOWN BUGS:
+
+Several tests in fmbtest.sh and foad1.sh fail under the cs_CZ.UTF-8 locale
+and have been disabled.
+
+The combination of -o and -i options is broken and the known failing cases
+are disabled in foad1.sh
+
+The option -i does not work properly in some multibyte locales such as
+tr_TR.UTF-8 where the upper case and lower case forms of a character are not
+necessarily of the same byte length.

+The development source code is available via Git from Savannah: see
+<https://git.savannah.gnu.org/cgit/grep.git>. The main project page is at
+<https://savannah.gnu.org/projects/grep/>.
+
+The source code in the Git uses autotools to generate some files. Before
+following the instructions in the INSTALL file for compiling grep, you
+need to run the bootstrap script.
+
+Please submit bug reports to <bug-grep@gnu.org>.
+
+If you are interested in the development of GNU grep, you may want to
+subscribe to the development mailing list. To subscribe, send an email

+quotation marks) in the subject header field (or in the body) of the

+
+To follow development more closely, there is also the grep-commit mailing
+list to which log entries (one per commit) and diff output (one per
+modified file) from CVS are automatically sent. To subscribe, send an
