# PCRE version 4.4 21-August-2003 # Tests taken from PCRE and modified to suit glibc regex. # # PCRE LICENCE # ------------ # # PCRE is a library of functions to support regular expressions whose syntax # and semantics are as close as possible to those of the Perl 5 language. # # Written by: Philip Hazel <ph10@cam.ac.uk> # # University of Cambridge Computing Service, # Cambridge, England.
