#   * Update lib/ruby-prof/version.rb
#   * Update CHANGES
#   * git commit to commit files

#   * rake compile to build windows gems
#   * rake package to create the gems
#   * Tag the release (git tag 0.10.1)

# it will push changes to github, tag the release, build the package and upload it to rubygems.org
