## DONE How to embed repositories without using submodules {#question-5414aee2-031a-5759-2a22-d572ee899ac0}
- DONE in 2021-08-04
By using a special `.gitdir` directory on the embedded repositories, the toplevel repository
can remain unchanged and include those.

I want to embed repositories so that I can use them in unit and integration
tests, but making them submodules makes the repository much less standalone than
I would like.
# Decisions
## DONE Perl vs C {#decision-d349b5be-3e00-4e00-a110-0eb7f402d4ab}
- DONE in 2021-05-28

Instead of Perl vs C, it became Perl vs Rust, and I've chosen Rust.
I choose Rust over C because it is a higher-level language than C is.
It allows me to produce binaries and libraries without extra dependencies (unlike C++'s `libstdc++`), and I can deal with memory management without reference counting (unlike Nim) or garbage collection (unlike D).
I'm favoring Rust as a C-like tool because it allows me to write code that transcends the language barries: with C/Rust code, a `.so` library can be consumed by any programming language on any environment.
The binary application that will be the CLI could be written in any language, also, but it is done so in Rust for convenience.
So the question of Perl vs C now is becoming applicable only on more specific scenarios: when having a `libsomething.so` isn't worth anything.
This isn't the case for this library.
