title: Ruby - adding a directory to $LOAD_PATH - what does it do?
body: <p>This is actually a question about this question: <a href="https://stackoverflow.com/questions/837123/adding-a-directory-to-load-path-ruby">Adding a directory to $LOAD_PATH (Ruby)</a></p>
  
  <p>What happens when you add a directory to the $LOAD_PATH? Is it like adding a script file to the execution context as in JavaScript? (You can access global methods/objects in another files) If not, how do I call the methods of other ruby files in the current directory?</p>
