Our first template follows a long noble tradition in computer tutorials. It produces a familiar, friendly greeting. Here's the template:
Hello, world!
... the output:
Hello, world!
... and the .py template module cheetah-compile produced, with line numbers added:

(I added the line numbers for this Guide, and split a few lines to fit the page width. The continuation lines don't have line numbers, and I added indentation, backslashes and '#' as necessary to make the result a valid Python program.)
The examples were generated from CVS versions of Cheetah between 0.9.12 and 0.9.14.
