Pattern for LaTeX environments is:
#+BEGIN_EXAMPLE
- \begin{NAME}
+ \begin{NAME}ARGUMENTS
CONTENTS
\end{NAME}
#+END_EXAMPLE
NAME is constituted of alpha-numeric characters and may end with an
asterisk.
+ ARGUMENTS is is any number (including zero) of ARGUMENT constructs
+ like ~[DATA]~ or ~{DATA}~. DATA can contain any character excepted
+ a new line or the one ending ARGUMENT.
+
CONTENTS can contain anything but the "\end{NAME}" string.
