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:

:package
Create all the requested package files.
:clobber_package
Delete all the package files. This target is automatically added to the main clobber target.
:repackage
Rebuild the package files from scratch, even if they are not out of date.
"package_dir/name-version.tgz"
Create a gzipped tar package (if need_tar is true).
"package_dir/name-version.tar.gz"
Create a gzipped tar package (if need_tar_gz is true).
"package_dir/name-version.tar.bz2"
Create a bzip2‘d tar package (if need_tar_bz2 is true).
"package_dir/name-version.zip"
Create a zip package archive (if need_zip is true).

Example:

  Rake::PackageTask.new("rake", "1.2.3") do |p|
    p.need_tar = true
    p.package_files.include("lib/**/*.rb")
  end
