Orgmode and Beamer

[David Masterson <dsmasterson92630@outlook.com>]

Does anyone have a recommendation on how to structure an Org document 
such that it can be exported to either Latex or Beamer? Suppose you have 
a (small) thesis that you are writing and you want to generate Beamer 
slides of a high-level view of the document, but also generate a PDF for 
the whole document.   I suppose you could break it into two files, but 
then you'd have to copy (certain) changes from file to file.  I was 
wondering if it could be done with one file such that updates to the 
master document are simultaneously reflected in the Beamer slides.  Is 
this going to involve liberal use of #+BEGIN...#+END blocks?
