GNU grep/egrep is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. GNU e?grep is brought to you by the efforts of several people: Mike Haertel wrote the deterministic regexp code and the bulk of the program. James A. Woods is responsible for the hybridized search strategy of using Boyer-Moore-Gosper fixed-string search as a filter before calling the general regexp matcher. Arthur David Olson contributed code that finds fixed strings for the aforementioned BMG search for a large class of regexps. Richard Stallman wrote the backtracking regexp matcher that is used for \<digit> backreferences, as well as the getopt that is provided for 4.2BSD sites. The backtracking matcher was originally written for GNU Emacs. D. A. Gwyn wrote the C alloca emulation that is provided so System V machines can run this program. (Alloca is used only by RMS' backtracking matcher, and then only rarely, so there is no loss if your machine doesn't have a "real" alloca.) Scott Anderson and Henry Spencer designed the regression tests used in the "regress" script. Paul Placeway wrote the manual page, based on the README.
