[Orgmode] Question on org-beamer markup

[Erik Iverson]

Hello,

According to http://orgmode.org/worg/org-tutorials/org-beamer/tutorial.html

the following markup should work when exporting to PDF from an 
org-beamer document.

- the first, very @important@, point!
- the previous point shows the use of the special markup which
  translates to the Beamer specific /alert/ command for highlighting
  text.

However, upon export the resulting .tex file does not actually contain 
this translation from @important@ to the alert command, but rather sill 
has @important@ in the output.

Am I missing some part of the setup process?

I am using the latest org pulled from git.

Thanks!
