   namespace Zoo;
   public interface IAnimal
   {
       string Name { get; set; }
       IFood FavorateFood { get; set; }
       void Speak();
   }
   
   public abstract class Mammal : IAnimal
   {
       public string Name { get; set; }
       public IFood FavorateFood { get; set; }
   
       public abstract void Speak();
   
       protected Mammal(string name, IFood favorateFood)
       {
           Name = name;
           FavorateFood = favorateFood;
       }
   }
   
   public class Cat : Mammal
   {
       public Cat(string name, IFood favorateFood) : base(name, favorateFood) {}
       public override void Speak()
       {
           Console.WriteLine("meow");
       }
   }
   
   public class Dog : Mammal
   {
       public Dog(string name, IFood favorateFood) : base(name, favorateFood) { }
       public override void Speak()
       {
           Console.WriteLine("woof");
       }
   }
   
   public interface IFood
   {
       string Taste { get; set; }
   }
   
   public class Fish : IFood, IAnimal
   {
       public string Taste { get; set; }
       public string Name { get; set; }
       public IFood FavorateFood { get; set; }
   
       public Fish(string taste, string name, IFood favorateFood)
       {
           Taste = taste;
           Name = name;
           FavorateFood = favorateFood;
       }
       public void Speak()
       {
           Console.WriteLine("...");
       }
   }
   
   public class Bone : IFood
   {
       public string Taste { get; set; }
       public Bone(string taste)
       {
           Taste = taste;
       }
   }

2. Run dll2mmd to generate output.md from Zoo.dll.

   $ dll2mmd -f Zoo.dll

3. output.md
