Re: Tangled Latex code gives error

I'm attracted to the tangle option because the normal latex export seems to
take everything in my .org file, e.g.,

* Introduction
LaTeX is a document markup language and a document preparation system
for the TeX typesetting program.

#+BEGIN_LaTeX
\begin{eqnarray*}
\hat{f}(x) & \propto & \sum_{\nu} \frac{|F(\nu)H(\nu)|^2}{|N(\nu)|^2}
           \frac{G(\nu)}{H(\nu)} e^{\frac{2 \pi i \nu x}{N}}\\
           & \propto & \sum_{\nu} \frac{|F(\nu)|^2}{|N(\nu)|^2} H(\nu)
H^*(\nu)
           \frac{G(\nu)}{H(\nu)} e^{\frac{2 \pi i \nu x}{N}}\\
           & \propto & \sum_{\nu} H^*(\nu) G(\nu) e^{\frac{2 \pi i \nu
x}{N}}
\end{eqnarray*}
#+END_LaTeX

will result in both the * Introduction blurb as well as the stuff between
the tatex "structural elements" being exported. With latex babel I can
tangle and get only what I want. This is handy if I want to throw around a
lot of chatter and extraneous stuff that ultimately I won't want in my
final document. We might call this "annotations a la orgmode." But, yes,
then I don't get the built-in orgmode latex support that comes with a
regular latex export. Please advise if I'm wrong on this understanding.
