+
+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.)

+
+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.
