Rails - Aug 2006 - init.rb

Hi folks,

Does anyone know of a "howto" or a good tutorial on how to write
init.rb files needed for distributing RoR applications?

I want to run:

1. tar2rubyscript application to produce
    application.rb
2. ruby application.rb to run it

The problem is I don''t know how to write init.rb for tar2rubscript to
bundle with my application.

Warm regards,

Bealach
