Universal Pluggable Logging Utility

The `log` package provides a universal and pluggable logging utility designed for JavaScript applications, currently stable at version 6.3.2. It focuses on being configurable, environment, and presentation agnostic, differentiating itself by not handling output directly but emitting events for external 'writers' (e.g., `log-node` for Node.js environments). Releases are made as needed, with several maintenance and minor feature updates occurring within the last few years. Key features include syslog-compatible log levels (debug, info, notice, warning, error), `debug`-style namespacing for granular control, and support for printf-like message formatting with various placeholders (e.g., `%s`, `%d`, `%j`, `%o`). This design allows developers to write application logs once and integrate different output mechanisms without changing core logging logic. It does not expose `critical`, `alert`, or `emergency` levels, expecting these to be handled as typical exceptions. A crucial differentiator is its modular approach, requiring an explicit 'writer' package to actually emit log messages, making it highly adaptable to various runtime environments and output formats.
