It is an excellent book, and well worth buying (actually I blagged
a review copy, but there you go). I would say you are well-nigh
guaranteed to learn things about regexps that you didn't know, no
matter how well-up on them you are. Procmail's regexps are supposed
to be compatible with egrep's, are they not? Egrep and friends
get quite a bit of in-depth coverage (not as much as Perl, though).
