# 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.

In practice, this means that if you use # PCRE in software that you distribute to others, commercially or # otherwise, you must put a sentence like this # # Regular expression support is provided by the PCRE library package, # which is open source software, written by Philip Hazel, and copyright # by the University of Cambridge, England. # # somewhere reasonably visible in your documentation and in any relevant # files or online help data or similar.
