def activate!
  require 'compass/import-once/activate'
end

.import_tracker ⇒ `Object`

A map of css filenames to a set of engine cache keys that uniquely identify what has been imported. The lifecycle of each key is handled by code wrapped around Sass’s render, to_css and render_with_sourcemap methods on the Sass::Engine.

Ideally, Sass would provide a place in it’s public API to put information that persists for only the duration of a single compile and would be accessible for all sass engines and sass functions written in ruby.
