- here's a key: value
  here's the first block: |
  after the block: value
  and here's a block: |-
    What's going on?
    How are you doing?
    Here's some code:
    
      #include <iostream>
      int main()
      {
         std::cout << "Hello World!\n";
      }
    
    I'm doing fine!
  and last key: value
