Skeleton for a simple ruby application.
Application is configured by environment.rb.
The configuration is described by config/config.yml
and accessible through Application.config.
config.yml can rely on ENV variables using the following syntax:
some_var: <%= ENV['SOME_VAR'] %>
In development, instead of exporting ENV variables,
they can be declared in config/application.yml:
SOME_VAR: __some_value__
app, lib and any (sub)folder of app/models are added to autoload_path.
Scripts in config/initializers are executed at the end application setup.
Rakefile sets up basics for rake tasks.
Any *.rake file in lib/**/tasks is loaded into rake.
Rakefile also provides a :environment task which provides a context
in which application is set up (config, access to models...).
