[tex-live] pretest: epstopdf overwrites existing files

[Karl Berry]

Hi Heiko and all,

    Or with option "append", it searches for PDF files first (and
    doesn't trigger the conversion if the PDF file exists.)

Thanks very much for that.  I've changed prepend to append in
graphics.cfg; that seems safer for the general TeX Live setting, while
still providing the conversion functionality in the common case.

FWIW, I did read the epstopdf documentation but did not figure out that
this was the implication of 
"Puts the extension .eps at the end of the graphics extension list".

A few extra words of explanation in the documentation would be welcome.
Even just "search" in front of "list".

(If you disagree, fine.  No need to reply. :)


Regarding people having trouble with the latex-l list: I too find the
latex-l listserv archives difficult to access.  My original message
(with some wrong assumptions) is
http://thread.gmane.org/gmane.comp.tex.latex.latex3/1465.
Heiko's message with the code that I imported into TL's graphics.cfg is
in that thread.
