This is a Ruby program that generates Scala program that generates Scheme program that generates ...(through 100 languages in total)... REXX 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 15.04 "Vivid Vervet", 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 \
ats-lang-anairiats bash bc bf boo bsdgames cduce clisp clojure1.6 \
cmake coffeescript dc ecere-sdk emacs24 erlang f2c falconpl \
fp-compiler fsharp g++ gambas3-script gap gauche gawk gcc gdc genius \
gforth gfortran ghc ghostscript gnat gnu-smalltalk gnuplot gobjc \
golang gpt gri groff groovy haxe icont iconx intercal iverilog \
jasmin-sable julia kaya libgd2-xpm-dev libpng12-dev lisaac llvm lua5.2 \
make maxima mlton mono-devel mono-mcs mono-vbnc nasm neko nickle ocaml \
octave open-cobol openjdk-6-jdk pari-gp parrot perl php5-cli pike7.8 \
python r-base ratfor regina-rexx rhino ruby2.1 scala scilab slsh \
spl-core swi-prolog tcl ucblogo valac xsltproc yorick zoem
Then, you have to build the bundled interpreters.
$ make -C vendor
To run it on Ubuntu 12.04 LTS, you might want to refer to .travis.yml.

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'm now writing "a book" about obfuscated programming. It will include a detailed explanation of how to write a quine, an ascii-art quine, and a uroboros quine like this quine-relay. It will be published in this year (if successful).
Bad news: It will be 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.

A. Do you try to cross the world line?
