There are a number of ways to indicate that a document should be  
typeset with xelatex instead of pdflatex, and that grep is meant to  
pick up the methods that I have seen in various places. Both the  
xunicode and fontspec[1] packages depend on xelatex, so calling on  
them (\usepackage{fontspec}) in your preamble should set DEF_TEX to  
xelatex. This is what I use to set it, because all my xetex documents  
make use of fontspec for easy font manipulation. But, some documents  
that I've seen have a line like the following:

%&program=xelatex

So the grep watches for that, as well.
