I browse with JavaScript off, and I can't scroll on that site. Could you degrade it more gracefully, please? It's a documentation site, after all, not something that should be design heavy.
Can you give a more elaborative example like how to print the output of ls command? Not a half baked example.
BTW why is not there in the By Examples page?
Examples are there to teach how stuff works, you can't be a programmer by copy-pasting everything. Read. learn and do it yourself. Maybe you can push it to Ballerina central as a library :)
