This library is a wrapper for the Exiftool command-line application (http://www.sno.phy.queensu.ca/~phil/exiftool/) written by Phil Harvey. It provides the full power of Exiftool to Ruby: reading and writing of EXIF-data, IPTC-data and XMP-data. Branch master is for actual development and branch compatibility-version is for compatibility with Ruby 1.8 and exiftool versions prior 7.65.
