This is a Ruby program that generates Scala program that generates Scheme program that generates ...(through 100 languages in total)... Rust program that generates the original Ruby code again.
(If you want to see the old 50-language version, see 50 branch.)
If you are using Ubuntu 17.04 "Zesty Zapus", you can perform the following steps.
First, you have to type the following apt-get command to install all of them.
$ sudo apt-get install afnix algol68g aplus-fsf asymptote ats2-lang bash \
bc bf bsdgames clisp clojure cmake coffeescript dafny dc ecere-dev \
elixir emacs24 erlang f2c fp-compiler fsharp g++ gambas3-script gap \

pari-gp perl php-cli pike8.0 python r-base ratfor regina-rexx ruby \
rustc scala scilab slsh squirrel3 swi-prolog tcl valac xsltproc yorick \
zoem
Then, build the bundled interpreters.

You will see that QR.rb is the same as QR2.rb.
$ diff QR.rb QR2.rb
Alternatively, just type make.
$ make
Note: It may require huge memory to compile some files.
Just install quine-relay-git from AUR and run quine-relay.
Report any problems as comments to the AUR package or to the respective packages, if one of the many compilers should have issues.
You may find instructions for other platforms in the wiki.
If you are not using these Linux distributions, please find your way yourself. If you could do it, please let me know. Good luck.

Note that some languages are not available in Ubuntu (marked as N/A).
This repository includes their implementations in vendor/.
See also vendor/README in detail.
A. Take your pick.
A. Good news: I published a book, "The world of obfuscated, esoteric, artistic programming". It explains how to write a quine, an ascii-art quine, and a uroboros quine like this quine-relay. You can buy my book on amazon.co.jp.
(It also contains my almost all (about forty) works, including alphabet-only Ruby program, radiation-hardened quine, etc., and explains many techniques to write such programs.)
Bad news: It is written in Japanese.
I hope you could translate it to English and help me earn royalties.
A. See the criteria for language inclusion in detail. (In short: please create a deb package and contribute it to Ubuntu.)
