title: R5RS Scheme input-output: How to write/append text to an output file?
body: <p>What is a simple way to output text to file in a R5RS compliant version of Scheme?
  I use MIT's MEEP (which uses Scheme for scripting) and I want to output text to file. I have found the following other answers on Stackoverflow:</p>
  
  <p><a href="https://stackoverflow.com/questions/4181355/file-i-o-operations-scheme">File I/O operations - Scheme</a></p>

  <p>But, they weren't exactly what I was looking for.</p>
