Yep, from test.js:

> const input = '(add 2 (subtract 4 2))';

> const output = 'add(2, subtract(4, 2));';

That's on lines 83/84. I'm not entirely sure that qualifies as the "top" of the source file. It's on the 4th page of the source file, given a traditional 80x25 terminal. (Assuming no wrapping, which the ascii art banner definitely could. A lot.)
