anchor.diff:  ** `.sti/bin/` - This folder contains scripts that are run by https://github.com/openshift/source-to-image[STI]:
   *** `assemble` - Is used to install the sources into location from where the application  will be run and prepare the application for deployment (eg. installing modules using npm, etc..).
   *** `run` - This script is responsible for running the application, by using the application web server.
  -*** `save-artifacts` - In order to do an *incremental build* (iow. re-use the build artifacts from an already built image in a new image), this script is responsible for archiving those. In this image, this script will archive all dependent modules.
   ** `ruby/` - This folder contains file with commonly used modules.
   ** `test/` - This folder is containing STI test framework with simple Rack server echo server.
   *** `test-app/` - Simple Rack server used for testing purposes in the STI test framework.
  
positive.code: * `hack/` - Folder contains scripts which are responsible for build and test actions performed by the `Makefile`.
  * `Makefile` - Make utility for simplifying image build and test actions.
