RegularExpressions tutorial / reference?

Here's a RegExp reference:
http://www.zvon.org/other/reReference/Output/index.html

Also, look at "Mastering Regular Expressions" by Jeffrey Friedl, published
by O'Reilly:
http://www.amazon.com/exec/obidos/ASIN/1565922573

Here are some tutorials:
http://www.linux-learn.org/regexp.tut
http://www.geocities.com/SiliconValley/Bay/3464/regex.htm
http://www.living-source.com/user/matte/regexp/regexp_tutorial.html
http://www.python.org/doc/howto/regex/regex.html

I haven't tries these yet (I'm still working through the book), so YMMV
