- 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 backreferencing
- 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.
