Package log provides a Logger primarily intended for terminal based command line programs. The logs it produces are semi-structured with key value pairs being formatted as key=value but are primarily intended to be human readable and easy on the eye with a good choice of colours, ideal for command line applications that have a --debug or --verbose flag that enables extra logging. log emphasis simplicity and efficiency so there aren't too many knobs to twiddle, you just get a consistent, easy to use, simple logger with minimal overhead.
