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Rebuild the package files from scratch, even if they are not out of date.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

Class Public methods
new(name=nil, version=nil)

Create a Package Task with the given name and version. Use :noversion as the version to build a package without a version or to provide a fully-versioned package name.
