This program has one goal in mind: to be accurate, readable, and minimal. It comes in three different versions: bf_long.ps is the full version equipped with debug tools and unit tests, bf.ps is a more readable version, and bf_tiny.ps is the minimal and “golfed” version, designed to be extremely compact. Whether you need a comprehensive and robust program or a concise and efficient one, this collection has got you covered.
