standalone running single file ( zipped archives of ruby code) running **without installation** using "gem install ..."
prior examples in other languages:

    python myprg.pyz
    java -jar myprg.jar

Detailed Description:
---------------------

In python, if i have multiple program files: "`a1.py`, `a2.py`, `__main__.py`,
  `dir1/b1.py`, `dir1/b2.py`" and then i zip it as myprogram1.pyz
then i can run it as "python myprogram.pyz" (`__main__.py` inside the zip
file will be executed first). It is easy to distribute a single file
myprogram1.pyz

see: http://blogs.gnome.org/jamesh/2012/05/21/python-zip-files/

---
in java also we can bundle all the .class files into a single .jar file
and run it

    java -jar myprogram1.jar

---
Currently in ruby the ".gem" file requires installation using "gem install ...". Then it gives some program file for running.
What i am asking is that some  gem file should have manifest with which they can run directly without installing


That is, i request you to kind provide a feature in ruby that if i have lots of files like: `a1.rb`, `a2.rb`, `__main__.rb`, `dir1/a4.rb` etc.
(say, which uses Ruby-GTK for a Desktop application). Then i should be able to bundle them as zip file, say myprog1.zip or myprog1.pz ( rbz=ruby's zipped executable archive).
And then i can distribute this "single file" and execute it as:

    ruby myprog1.rbz

This will execute the `__main__.rb` file among all the other .rb files,
inside this .zip archive myprog1.rbz  .
Note: this .rbz file extension can be .gemz or whatever, but this functionality of "standalone running zipped archives of ruby code running without installation" is essential
