summary

pros● fast

● easy to extend

● expressive

● polyglot

● wysiwyg

cons● ruby knowledge

● pure IDE support

when to use?● need to easily tweak build/automation

● need flexibility in configuration

● need speed

● or you need something new

when not to use?● in tough time-line

● your current build is over-customized

● team does not want to learn ruby
