  42. <h2>About brainfuck</h2>
    43. 

  43. <p><a href=http://esolangs.org/wiki/Brainfuck>Brainfuck</a> <i>(not capitalized except at the start of a sentence)</i> is an esoteric programming language. It has eight commands — <code>+-&lt;>[],.</code> — and ignores all other characters. As a result, no special syntax for comments is needed, as long as the comments don’t contain the command characters.
