Harnessing ExifTool Output

I capture the output of some command-line programs by redirecting their output to a temp file and then reading the temp file.  That seems to be portable between Windows and Mac (though I haven't tested it yet with Mac).   Exiftool uses standard error as well as standard out, so to capture both in the same file, you'll need to do something like:

exiftool ... > output.log 2>&1

The "2>&1" supposedly has to go last on the command line on Windows.

I looked into capturing the output of Exiftool using the -X option, which writes XML output, and then using the SDK's LrXml to read it.  But I ended up not needing to go that route and don't have any meaninful experience to report.
