+%description
+diffoscope will try to get to the bottom of what makes files or directories
+different. It will recursively unpack archives of many kinds and transform
+various binary formats into more human readable form to compare them. It can
+compare two tarballs, ISO images, or PDF just as easily. The differences can
+be shown in a text or HTML report.
+
+diffoscope is developed as part of the "reproducible builds" Debian project and
+was formerly known as "debbindiff".
