Hi Doug: We pretty much rely upon you for Perl/PDL expertise so I assume you will be doing most of the Perl/PDL maintenance of the examples in any case. After a round of such maintenance I would encourage you to go ahead and copy those updated examples from PLplot to the PDL::Graphics::PLplot package since those examples are useful documentation of how to use PDL::Graphics::PLplot. If you try your md5sum idea, then probably PostScript results from the psc device (with datestamp excluded which can be straightforwardly arranged) or SVG results from the svg device are the ones you should use. Both those file devices have no external dependencies, and they are much better maintained than the xfig device. Hopefully, you will find the md5sum will be invariant from one platform to the next for all our test example results. That depends on whether platform floating-point differences propagate to the rounded results in PostScript (or SVG) results or not, but you will have to find that out by experiment.
