does this work with the Windows executable version? Is this a PERL script? Do I need to learn PERL to use this capability? Where is the config file documentation (I could only find the sample config file)?
Please pardon me these questions, but I am very interested, this could help me tremendously. Currently I am using shell scripts (with all the trouble on Windows) and batch files and have to call exiftool several times for each image. With user-defined tags, it seems, one could just use one call to exiftool and get a substantial speed up.
