title: Linux custom executable globally available
body: <p>I downloaded the Google App Engine as a zip format, unzipped it to /usr/local/google_engine</p>
  
  <p>Now I need to run a python script from that folder all the time. How do I make it available no matter where my path is? ie: when i'm in /usr/something/ i can execute the script by just calling script.py?</p>
  
  <p>Can I do this without aliasing or without using bash scripts?</p>
