1*a8fa202aSchristosThis is GNU grep, the "fastest grep in the west" (we hope). All 2*a8fa202aSchristosbugs reported in previous releases have been fixed. Many exciting new 3*a8fa202aSchristosbugs have probably been introduced in this revision. 4*a8fa202aSchristos 5*a8fa202aSchristosGNU grep is provided "as is" with no warranty. The exact terms 6*a8fa202aSchristosunder which you may use and (re)distribute this program are detailed 7*a8fa202aSchristosin the GNU General Public License, in the file COPYING. 8*a8fa202aSchristos 9*a8fa202aSchristosGNU grep is based on a fast lazy-state deterministic matcher (about 10*a8fa202aSchristostwice as fast as stock Unix egrep) hybridized with a Boyer-Moore-Gosper 11*a8fa202aSchristossearch for a fixed string that eliminates impossible text from being 12*a8fa202aSchristosconsidered by the full regexp matcher without necessarily having to 13*a8fa202aSchristoslook at every character. The result is typically many times faster 14*a8fa202aSchristosthan Unix grep or egrep. (Regular expressions containing backreferencing 15*a8fa202aSchristoswill run more slowly, however.) 16*a8fa202aSchristos 17*a8fa202aSchristosSee the files AUTHORS and THANKS for a list of authors and other contributors. 18*a8fa202aSchristos 19*a8fa202aSchristosSee the file INSTALL for compilation and installation instructions. 20*a8fa202aSchristos 21*a8fa202aSchristosSee the file NEWS for a description of major changes in this release. 22*a8fa202aSchristos 23*a8fa202aSchristosSee the file TODO for ideas on how you could help us improve grep. 24*a8fa202aSchristos 25*a8fa202aSchristosSend bug reports to bug-grep@gnu.org. 26
