# Release Engineering:
#   1. edit the VERSION.yml file
#   2. rake compile  &&   rake test   &&   rake build
#      to generate pkg/sekka-x.x.x.gem
#   3. install sekka-x.x.x.gem to clean environment and test
#   4. rake release
#   5. gem push pkg/sekka-x.x.x.gem   ( need gem version 1.3.6 or higer. Please "gem update --system" to update )
