title: How to compile/run Ada on mac
body: <p>I downloaded the Ada language, the GNAT compiler, textwrangler, and xcode on my mac os x version 10.6.8. I am writing Hello World in textwrangler and now need to compile, build, and run the program. This is where I am stuck. </p>
  
  <p>Questions:
  A: How do I compile and run my simple program? 
  B: Can you show me how to do this via Terminal as well as another option?
  C: Can/should this all be done through xcode instead?</p>
  
  <p>Here is all of the code I have in the textwrangler document:</p>
  
  <pre><code>WITH Ada.Text_IO;
  USE Ada.Text_IO;
  
  PROCEDURE Hello IS
  BEGIN
     Put("Hello World");
  END Hello;
  </code></pre>
