+module Rake
+
+  # Create a packaging task that will package the project into
+  # distributable files (e.g zip archive or tar files).
+  #
+  # The PackageTask will create the following targets:
+  #
+  # [<b>:package</b>]
+  #   Create all the requested package files.
+  #
+  # [<b>:clobber_package</b>]
+  #   Delete all the package files.  This target is automatically
+  #   added to the main clobber target.
+  #
+  # [<b>:repackage</b>]
+  #   Rebuild the package files from scratch, even if they are not out
+  #   of date.
+  #
+  # [<b>"<em>package_dir</em>/<em>name</em>-<em>version</em>.tgz"</b>]
+  #   Create a gzipped tar package (if <em>need_tar</em> is true).  
+  #
+  # [<b>"<em>package_dir</em>/<em>name</em>-<em>version</em>.tar.gz"</b>]
+  #   Create a gzipped tar package (if <em>need_tar_gz</em> is true).  
+  #
+  # [<b>"<em>package_dir</em>/<em>name</em>-<em>version</em>.tar.bz2"</b>]
+  #   Create a bzip2'd tar package (if <em>need_tar_bz2</em> is true).  
+  #
+  # [<b>"<em>package_dir</em>/<em>name</em>-<em>version</em>.zip"</b>]
+  #   Create a zip package archive (if <em>need_zip</em> is true).
+  #
+  # Example:
+  #
+  #   Rake::PackageTask.new("rake", "1.2.3") do |p|
+  #     p.need_tar = true
+  #     p.package_files.include("lib/**/*.rb")
