This script depends on:

• cargo-download
• A Debian/Ubuntu Linux flavored tar command

This is a script that scrapes all the crates based on crates.io inside a Cargo.lock file and stores them locally. It also can perform a quick "analysis" which simply looks for all the build.rs scripts and collates them into a single file for quicker and easier inspection of what all the build.rs scripts are trying to run on your local machine.

The repo is committed with the fetched artifacts, so we have some traceability in terms of looking at what happened in a given Xous build. Ideally this script is run once every tagged release cycle and the files are re-committed in this repo.

It's fairly heavy-weight and a work in progress so it's not integrated into the CI flow (yet). Perhaps once this has matured a bit and I have a better idea of exactly what I'm looking for, this will get integrated into the CI flow. But for now, this lets me put a pin in the source files that are involved in building xous-core such that I can look at them later in case there's any problems.

Here's a log of all the times this has been run:
