Hi:

If possible, please merge this patch to master, thanks!


I think it is a way reusing the exist class defines in `org-latex-classes
If your class is similar with a exist one, 

For example:

#+begin_example

("article"
     "\\documentclass[11pt]{article}"
     ("\\section{%s}" . "\\section*{%s}")
     ("\\subsection{%s}" . "\\subsection*{%s}")
     ("\\subsubsection{%s}" . "\\subsubsection*{%s}")
     ("\\paragraph{%s}" . "\\paragraph*{%s}")
     ("\\subparagraph{%s}" . "\\subparagraph*{%s}"))

("ctexart"
     "\\documentclass[11pt]{ctexart}"
     ("\\section{%s}" . "\\section*{%s}")
     ("\\subsection{%s}" . "\\subsection*{%s}")
     ("\\subsubsection{%s}" . "\\subsubsection*{%s}")
     ("\\paragraph{%s}" . "\\paragraph*{%s}")
     ("\\subparagraph{%s}" . "\\subparagraph*{%s}"))

#+end_example

You don't need to add  "ctexart" to `org-latex-classes,

just type:

#+LATEX_CLASS: article
#+LATEX_CLASS_NAME: ctexart
