reprotest builds the same source code twice in different environments, and
then checks the binaries produced by each build for differences. If any are
found, then diffoscope (or if unavailable then diff) is used to display them
in detail for later analysis.
It supports different types of environment such as a "null" environment (i.e.
doing the builds directly in /tmp) or various other virtual servers, for
example schroot, ssh, qemu, and several others.
reprotest is developed as part of the "reproducible builds" Debian project.
