Guide lines for developing MT systems:

• Make complete information available to the user
  but, do not clutter the scene.
  
                    ----- Reversibility
                    ----- Hiding Mechanism/User Interface


• Seperate the resources
  that can be made, in principle, reliable
  from those that are, inherently unreliable.
  mention the degree of reliability explicitly.
  
                    ----- Change the Ordering of Operations


• provide alternative means to get the information
  
                    ------ Online help
                ------ Human readable algorithms


• Do not reinvent the wheel
  
                    ------ Resort to GPL


• Use existing resources and tools
  
                    ------ Develop suitable interfaces for 'plug and test' of different tools
                    ------ Use best of K result to improve the performance
