I would be more interested in a "what I like about it" sentence over a preemptively pacifying "to each their own" tbh. The tool's own description doesn't compare against exiftool either, besides that it sounds like it does only images and not, e.g., documents

> Exiv2 is a C++ library and a command-line utility to read, write, delete and modify Exif, IPTC, XMP and ICC image metadata.
