What is Dime?
It is a state oriented language. Voices apps are modelled as state machines, which is a common practice in this field.
How it works?
Once you develop a Dime app, you can generate (without extra coding!) the code for Tropo (or Twillio) and deploy your app. So, you can save your investment and avoid developing the same application for different clould voice platforms.
In addition to XText, Dime uses other frameworks, such as Sinatra and Limonade for the state machine.
What can be done?
Even though Dime seems very simple, Dime can be very productive and be used for developing rather complex applications in just few lines. For example, you can develop very easily a voice app for voice-based restaurant booking This app can be later deployed in a web server or integrated into an Android app!
