def directory(target, options={})
  target = File.expand_path(target)
  
  case
  when File.exists?(target)
    log_relative :exists, target
  else
    log_relative :create, target
    FileUtils.mkdir_p(target) unless pretend
  end
end

#file(target, options = {}) {|source_file| ... } ⇒ Object

Creates the target file; content may be added to the file by providing block. If the target file already exists, the new and existing content is compared and the user will be prompted for how to handle collisions. All activity is logged. When pretend is true, creation is logged but does not actually happen.

No options currently affect the behavior of this method.

Yields:

  • (source_file)
