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.
