title: How to make a call from one Google Apps Script to a function in another?
body: <p>Is there an easy way of making a call from one Google Apps script to a function in another? </p>
  
  <p>I'm writing two scripts, one which should use functions from the other. I want the two to have different sharing permissions, however, so I don't want to put them in the same project.</p>
  
  <p>I can't seem to find any "require Xxx.gs" type function in the documentation.</p>
  
  <p>I found this:
  <a href="https://stackoverflow.com/questions/11335646/call-functions-from-another-class-file">Call functions from another &quot;class&quot; / file</a></p>
  
  <p>But I get "xxx function not found" errors if I try to call a function from a different file.</p>
