@fazalmajid It installs rbtlog and tools. That's what we use to verify whether apps can be built reproducible (i.e. byte-identical), thus confirming they were really built from the very source code they claim, with nothing added or taken away.

Apart from that, developers can also use this to just build their apps, ensuring they are always built from a clean tree at the specified commit, and thus making RB easier.

Proper documentation is still on our roadmap; until then: https://gitlab.com/IzzyOnDroid/repo/-/wikis/Reproducible-Builds
