# Create a package based upon a Gem spec. Gem packages, as well as
# zip files and tar/gzipped packages can be produced by this task.
#
# In addition to the Rake targets generated by PackageTask, a
# GemPackageTask will also generate the following tasks:
#
# [<b>"<em>package_dir</em>/<em>name</em>-<em>version</em>.gem"</b>]
# Create a Ruby GEM package with the given name and version.
#
# Example using a Ruby GEM spec:
#
# require 'rubygems'
#
# spec = Gem::Specification.new do |s|
# s.platform = Gem::Platform::RUBY
# s.summary = "Ruby based make-like utility."
# s.name = 'rake'
# s.version = PKG_VERSION
# s.requirements << 'none'
# s.require_path = 'lib'
# s.autorequire = 'rake'
# s.files = PKG_FILES
# s.description = <<EOF
# Rake is a Make-like program implemented in Ruby. Tasks
# and dependencies are specified in standard Ruby syntax.
