org-article.cls

[azubi]

Hi,

Could someone help me to generate or find the file org-article.cls.

I've found a git repository wich provides an org file with commented 
sources of the file "org-article.cls".

(see: http://orgmode.org/worg/org-contrib/babel/examples/article-class.html)

The documentation says that the cls file may be generated from the file 
org-article.org. But, if I "tangle" (sorry for my bad english) this 
file, emacs generates a file called org-article.cls which is almost 
empty (it contains only spaces and "new lines").



It seems that the new version of org-mode does need this latex class 
anymore. Therefore I'd like to ask a second question:

The latex document generated by org-mode (org-latex-export-to-pdf or 
org-latex-export-to-latex) is not what I need. Many latex packages 
included by default (for example textcomp, marvosym, wasysym) conflict 
with packages I'd like to use (for example kpfonts). Can you please give 
me a pointer to a doc where I learn to customise the latex export of 
org-mode without editing the original org-mode source files.


Thank you in advance for your help!
