prompt: Your task is to convert the following English description into an ASCII tree format.
  
  base is a head directory that holds 4 subdirectories. Notable ones include binary, component, internal among others.
  
  Let me break down the design for you:
  
  In the root directory, Inside 'binary', you'll find it is an empty container.
  At the main level, The 'component' folder contains no subdirectories.
  At the main level, 'internal' hosts 2 subdirectory elements: registry, toolchain.
  In nested path 'internal > registry', 'registry' appears to be unused.
  Within directory hierarchy 'internal → toolchain', 'toolchain' is an empty container.
  At the main level, 'plugins' contains nothing at present.
  
  
  Format your response in this style:
  ```
