cargo-c VS gentoo

I'm writing this to explain some of the problems cargo-c solves and hopefully give few pointers since the README containing all the documentation maybe grew to be fairly big.

Beside rav1e there is need also for cargo-c, so that rav1e can provide C-compatible library.

When I notice some rust software sporting a C-API that I'd consider packaging in Gentoo I tend to provide a patch to add the few metadata entries needed to have cargo-c do all the work, some other people politely ask if cargo-c is supported and sometimes it is an uphill battle usually because the project maintainer doesn't know the required effort is minimum or is not aware setting crate-type=cdylib is not enough.

What thinly separates distros (apart from the GUI) is the package manager (PM). There are two main distinctions: source and binary based. Source-based distros are managers that download the source files, and then build them while following their recipes. We must build everything ourselves, including the core system components. The most notable examples come from the Berkeley Software Distribution (BSD) family and Gentoo from Linux. Some BSD forks try to be more user friendly, and there are also forks of Gentoo available. These are geared toward easier maintenance for their dev team.

Their images are Debian derivatives, I prefer Gentoo and since we have stage3 for rv64_lp64d-openrc, I guess I can give it a try.

> Gentoo does not accept art contributions of any kind (human/ai), there is just no place for this.

Okay, let's do a short fact check on that:

1. Visit https://gentoo.org, notice logo in top left: a first sign of contributed art.

sync-depth = 1 sync-type = git auto-sync = yes location = /var/db/repos/gentoo sync-git-verify-commit-signature = yes sync-openpgp-key-path = /usr/share/openpgp-keys/gentoo-release.asc sync-uri = https://github.com/gentoo-mirror/gentoo.git ```

eselect repository add gentoo git https://github.com/gentoo-mirror/gentoo.git

And just wait till you discover Arch Linux, Gentoo, Guix, or NixOS.

I'm daily driving Gentoo GNU/Linux (https://gentoo.org). I prefer it over other GNU/Linux distributions because it allows me to customize the operating system down to a lower level. I'm also planning on installing Linux From Scratch (https://linuxfromscratch.org) for educational purposes. However, I might end up daily driving it. I do extremely difficult and tedious activities on my computer just for fun and I also happen to have a lot of free time. So don't question my choice of operating systems.
