In many outerthemes (i.e., the beamer header and footer formatting), the
"short" version of title, author, institution, and date are used. While
this is the (my) primary use case I can think of, the positioning
<something other than>BEAMER_HEADER_EXTRA serves as final preamble
injection point. I just reread your discussion with Sebastien [1] and agree
the proposed name is bad.

From what I can tell, the current ox-beamer.el does not support beamer's
institution macor or the short version of title, author, institution or
date. I can think of two options to get around this:

   - do not use #+Title, etc., and simply use BEAMER_HEADER or similar
   - use #+Title plus something like this patch to inject fixes *after*
   \title

As a user, I prefer the latter, because it maximizes the portability of my
code (so I can use something like org-reveal [2]).

Another option would be to simply move BEAMER_HEADER to inject code where I
have implemented BEAMER_HEADER_EXTRA. That would provide the same
functionality with a reasonable name. I still need to better format my
commit message (I forgot to before submitting), so I can make any other
updates that are deemed necessary.

Let me know what you (and others) think.

Cheers,
Matt
