[XeTeX] ifxetex package

[Will Robertson]

Hello,

Note that there is now a very simple package on CTAN called ifxetex:
   <http://tug.ctan.org/tex-archive/macros/xetex/latex/ifxetex>

It can be used for either LaTeX or Plain (or ConTeXt) to provide the  
\ifxetex conditional, a la ifpdf. All (4) XeTeX package writers take  
note :)
