    def prepare
    end

run(run_options = {}) click to toggle source

Runs the installer. Every installer must conform to the installation strategy of prepare, install, and then finalize. A default implementation is provided for each step.

    def run(run_options = {})
      prepare unless run_options[:skip_preparation]
      install unless options[:prepare]

    end

stylesheet_links() click to toggle source

returns an absolute path given a path relative to the current installation target. Paths can use unix style "/" and will be corrected for the current platform.

    def targetize(path)
      strip_trailing_separator File.join(target_path, separate(path))
    end
