Thanks Nick, for the more helpful explanation than mine ;)

The function I provided is part of this file:
https://github.com/jkitchin/jmax/blob/master/ox-manuscript.el

which I have been working on for publishing scientific manuscripts. This
file provides a new export menu option that not only removes the extensions
in the latex file, but also replaces the \bibliography{} line with the
contents of the .bbl file so that you have a single, standalone tex file
for submission. There is even an export and mail option for a pdf ;)

With this library installed, you can just type: C-c C-e j m
to build your latex file with extensions removed, bibliography replaced,
and open the pdf through the regular org-mode export menu. This may be more
helpful than trying to do the steps manually as I described.
