title: How do I include functions from another file in my Perl script?
body: <p>This seems like a really simple question but somehow my Google-Fu failed me.</p>
  
  <p>What's the syntax for including functions from other files in Perl?  I'm looking for something like C's <code>#include "blah.h"</code></p>
  
  <p>I saw the option for using Perl modules, but that seems like it'll require a not-insignificant rewrite of my current code.</p>
