RELAX NG book, very cheap

Please pardon this semi-commercial moment from an involved party, but
for some reason Amazon's discounted the RELAX NG book by 60%, dropping
it to US$11.98.

For a recently-published 500-page computer book, this is shockingly
cheap. (It's normally $29.95.)  Of course, you can also get the text for
free (under the GFDL) at:

but paper has its virtues.

We now return to our usual programming.
