## What it is
A Ruby program that generates a Rust program that generates a Scala program, and so on through 128 programming languages, eventually reproducing the original Ruby code. It is a recreational 'uroboros quine' demonstrating an enormous multi-language self-reproducing program chain.

## Use cases
- explore how quines work across many languages
- see the same program written in 128 programming languages
- recreational programming challenge or demo
- learn about self-reproducing programs
- test that many compilers and interpreters are installed correctly

## When to choose
- you want a fun, extreme example of a quine spanning many languages
- you are studying quine construction techniques
- you want a stress test for a large set of installed compilers and interpreters

## When to avoid
- you need a practical tool or library for production use
- you want a simple, small quine to learn from
- you need software with a license for redistribution

## Facets
- artifact type: learning-resource
- maturity: active
- function: interpreter, compiler, programming-language
- domain: programming-languages, education
- platform: cli
- tags: quine, esoteric, novelty, polyglot, recreational-programming, algorithms, linux
