|  Hi all,
|  I've been using a script to generate both eps and pdf versions of a
|  PSTricks graphic.  Does a macro exist to include one or the other,
|  depending on whether I'm using LaTeX or pdfLaTeX?

I'm not sure if this has been fixed, but \includegraphics without an
extension most certainly does *not* always choose the right file.
That approach only works if the filename does not contain any periods,
because it treats anything after the period as part of an extension,
instead of just using the .pdf or .eps part.  I've got hundreds
(thousands) of legacy image files using periods for many different
purposes, so I had to write my own macros that wrap around
\includegraphics to fill in the appropriate extension.
