how to write a tutorial

[Xah Lee]

i've noticed that in Python official doc
http://python.org/doc/lib/module-re.html
and also How-To doc
http://www.amk.ca/python/howto/regex/

both mentions the book "Mastering Regular Expressions" by Jeffrey
Friedl.

I suggest it be dropped in both places. The mentioning of this book in
the Perl/Python community is mostly a fawning behavior and confession
that the author is among "in the know". This book and its mentioning is
a cultish behavior among OpenSource morons.

Most of the time, its mentioning as a reference is irrelevant. 99% uses
of regex are the simplest uses. Spending time to read this book of
specialization, from economy perspective, is a waste of time.
