I love PCRE since it gives tou both, a POSIX compatible library
_and_ perlish extensions. A few things to consider: 

 - Licence. Iff used with GPL/LGPL software than this seems to
   be no problem because the licence (
   states that in case of conflict GPL rules (yeah!).
   But for those that use LibXSLT/libXML under the alternative
   W3C IPR this would mean inclusion of another licence. Just some-
   thing to consider.

 - Multibyte string support. How well does the PCRE library handle this.
   I haven't used it in recent projects but recall that there was a
   pecularity using the repeat characters '+' and '*'. I'm sure
   Philip Hazel will work on this.
