Ouch. All of a sudden some of the problems I had with regexp and
cfengine also make sense.

In view of this, having support for the PCRE library would be a very
good thing, I feel. It would make the tool consistent across platforms
as well as providing a good, fairly well known regexp implementation.

Alternately, using the GNU rx library on all platforms would be good,
since that would have the same effect, even if it is not quite such a
nice engine...
