[mojomojomojo]

These are the two command-line parameters for which it is feasible to construct deterministic tests.

Out of curiosity, why is this a separate repo?

Thank you for this! I will try to make time to look at this and other PRs soon.

Out of curiosity, why is this a separate repo?

The files here are somewhat big and are binary files, people who just want to build Very Sleepy shouldn't be forced to download them (especially as Git will download all past versions of them by default).

Won't the git submodule things built into the main repo download them anyway? I mean, it seems like a standard thing to get all the submodules. I had to do that in order to build at all.

Only if you clone with --recursive, and you can select which submodules to fetch if you want to. You can't really pick and choose when everything is in one Git repo, though.
