  Regular expressions are a very powerful tool - and well integrated
into Perl - but there is a learning curve.  I learned a lot about them
from Unix and Perl books - but then read

Mastering Regular Expressions by Jeffrey E.F. Friedl

and that *really* helped! I strongly recommend this book if you want to
reap the full benefits of using regular expressions.
