I've updated the script. It can handle logarithmic y-axes now,
autmatically detects the color of the error band, and is generally much
smarter with finding the points and the error bands in the postscript
code. Now it actually works on ATLAS-CONF-2010-049 (fragmentation
function inside jets), too, and probably on other analyses, though the
fragmentation function analysis is the only one I've tried.
