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.

It can be scripted through error codes, and a report can be produced
with the detected differences. The report can be text or HTML.
When no type of report has been selected, diffoscope defaults
to write a text report on the standard output.

diffoscope will exit with 0 if there's no differences and 1 if there
are. An HTML report can be produced with the detected differences.

diffoscope is developed as part of the "reproducible builds" Debian
project.
It is meant to be able to quickly understand why two builds of the same
package produce different outputs. diffoscope was previously named
debbindiff.
