dmg2img converts compressed Apple DMG archives to standard HFS+
disk images. It supports zlib and bzip2 compressed images. The package
also includes vfdecrypt, a utility for decrypting encrypted DMG files.

The original upstream 1.6.7 source archive is no longer available. This
SlackBuild uses the Ubuntu source archive containing the same upstream
snapshot from 2020-12-27, at Git commit a3e4134.
