Documentation Generators for Unity code comments

Are you using C# or Unityscript? If you are working with C# Doxygen is a great solution. You can also use XML style comments and export MSDN-like documentation from within Visual Studio.

For UnityScript the only workable solution I have found is: YUIDoc

For C# you have many more options. I have used Doxygen in the past and I have liked the results.
