Aloha Eric Fraga,

Is it OK with you to put a modified version of the emacs-lisp code for  
LaTeX GANTT charts in the Library of Babel?  I agree with Eric S. (see  
below) that this would be the best location for it in the context of  
org-article.cls.

You can see my version of your code here:

http://orgmode.org/worg/org-contrib/babel/examples/article-class.php#sec-3_4_5_1

My changes to your code were minor.

1) I've taken off the header arguments.   AFAICT, header arguments in  
the Library of Babel aren't used as the defaults when the function is  
called, so there is no reason to have them there in this context.

2) I've taken out the code that generates #+begin_latex and # 
+end_latex.  This makes it possible to use the function in the Org- 
mode buffer:

#+lob: elispgantt(table=gantttesttable) :results output latex

and also within a LaTeX source code block:

#+lob: elispgantt(table=gantttesttable) :results output raw

Thanks very much for the useful code, BTW.  We're writing an annotated  
bibliography of Hawaiian history at work and I'm pretty sure we can  
use a GANTT chart to show a timeline of historians over the last  
century and a half.

All the best,
Tom
