def config
  @config ||= begin

end

.gem_root ⇒ Object

Provides the root to Docker template, wherever it is installed so that we can do things, mostly ignore files for the profiler. Otherwise it’s not really used, it’s just an encapsulator.

end

.repos_root ⇒ Object

The location of the standard repos/ dir, you can change this by adding repos_dir into your configuration file. I’m not saying it has to be but it should probably be relative rather than absolute, ther are no guarantees that an absolute path will work.
