Hi,

I am writing a small program using org-babel as a literate programming
tool.  When I exported the file to LaTeX, it could not compile.  The
problem is that the code blocks are surrounded by \begin{\LaTeX{}} and
\end{\LaTeX{}}, which is an unknown environment to LaTeX.  A small
example follows.

The org file contains:

#+srcname: determine the neighbors of the segments that the bisector hits
#+begin_src lua :tangle no :exports code
  local s1, s2 = intersecting_segs[1], intersecting_segs[2]
  local n1 = table_find_segment(cell.neighbors, s1)
  local n2 = table_find_segment(cell.neighbors, s2)
#+end_src

and the output .tex file contains:

\begin{\LaTeX{}}
\begin{verbatim}
local s1, s2 = intersecting_segs[1], intersecting_segs[2]
local n1 = table_find_segment(cell.neighbors, s1)
local n2 = table_find_segment(cell.neighbors, s2)
\end{verbatim}
\end{\LaTeX{}}

I haven't tried this without using org-babel, so I can't say whether
the problem is with org-babel or just with the LaTeX exporter.

Cheers,
Chris
