wtf is log?

This is a logging package for Go applications that makes it easier to handle logs in production environments. Instead of using Go's basic built-in logging tools, which lack important features like automatic log file rotation, this package bundles together all the logging capabilities that enterprise applications typically need. The package works by letting you configure where logs go (to a file, to your console, or both) and what information gets recorded (different severity levels like debug, info, warning, and error). You set it up once with a configuration file, then use simple commands like log.Info() or log.Error() throughout your code. When your log files get too large or too old, the system automatically compresses and archives them, keeping your disk usage under control and making it easy to find historical logs. A developer building a real production application would use this instead of Go's standard logging tools because it handles all the tedious operational stuff automatically. For example, if you're running a service that needs to log thousands of requests per day, this package will split your logs into separate files by day (or by size), archive old ones, and let you keep only the last seven backups. You configure all this behavior in a simple YAML file, so you don't need to write custom rotation code yourself. The README notes that this package was tested to handle enterprise-level performance demands, meaning it's fast enough for high-traffic systems. The package is based on an earlier project and streamlines its approach to be simpler to use, while keeping the same core functionality. You initialize it once at startup, point it at your configuration file, and then your entire application can log consistently without any additional setup.
