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.) 1.18 + 1.19 +Send bug reports to bug-grep@gnu.org. 1.20 + 1.21 + 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.
