In your home directory, make a new directory named aspentut. Create a file in aspentut named index.html, with the following contents:
Greetings, program!
At the command line in the aspentut directory, type aspen. You
should get output like this:
$ aspen
aspen starting on ('', 8080)
Now open a web browser and hit http://localhost:8080/. You should see
"Greetings, program!" in your browser. Congratulations!
