Docker iamge for diffoscope

diffoscope is a great tool for comparing files and directories recursively. It supports a variety of different file formats.

Problem

The image built by official Dockerfile is quite huge. I tried to containerize it with Archlinux with some useful dependencies.

$ docker images
REPOSITORY                                                 TAG                 IMAGE ID            CREATED             SIZE
xatier/diffoscope-arch                                     latest              647ad3f846af        16 minutes ago      1.34GB
archlinux/base                                             latest              754519a037bc        2 weeks ago         459MB
registry.salsa.debian.org/reproducible-builds/diffoscope   latest              b400779127a1        2 weeks ago         3.69GB
