     1.4 +This is GNU grep, the "fastest grep in the west" (we hope). All bugs reported
     1.5 +in previous releases have been fixed. Many exciting new bugs have probably been
     1.6 +introduced in this revision.
     1.7 +
     1.8 +GNU grep is provided "as is" with no warranty. The exact terms under which you
     1.9 +may use and (re)distribute this program are detailed in the GNU General Public
    1.10 +License.
    1.11 +
    1.12 +GNU grep is based on a fast lazy-state deterministic matcher (about twice as
    1.13 +fast as stock Unix egrep) hybridized with a Boyer-Moore-Gosper search for a
    1.14 +fixed string that eliminates impossible text from being considered by the full
    1.15 +regexp matcher without necessarily having to look at every character. The
    1.16 +result is typically many times faster than Unix grep or egrep. (Regular
    1.17 +expressions containing backreferencing will run more slowly, however.)

    1.22 +KNOWN BUGS:
    1.23 +
    1.24 +Several tests in fmbtest.sh and foad1.sh fail under the cs_CZ.UTF-8 locale
    1.25 +and have been disabled.
    1.26 +
    1.27 +The combination of -o and -i options is broken and the known failing cases
    1.28 +are disabled in foad1.sh
    1.29 +
    1.30 +The option -i does not work properly in some multibyte locales such as
    1.31 +tr_TR.UTF-8 where the upper case and lower case forms of a character are not
    1.32 +necessarily of the same byte length.
