## What it is
Seelog is a native Go logging library providing flexible asynchronous dispatching, filtering, and formatting of log messages. It supports XML-based configuration, hot-reloading of config, multiple output writers (console, file, rolling, SMTP), and adjustable formatting.

## Use cases
- log messages from a Go application with configurable formats
- configure logging via XML without recompiling
- write logs to multiple destinations simultaneously
- rotate log files automatically
- change logging configuration at runtime without restart
- minimize logging performance overhead with async dispatch

## When to choose
- you need flexible, XML-configurable logging in Go
- you want async logging with multiple writers and rotation
- you need per-file or per-function log configuration

## When to avoid
- you want a actively developed library with recent releases
- you prefer structured logging with modern Go logging standards like slog
- your project needs long-term community support

## Facets
- artifact type: library
- maturity: maintenance
- function: logging
- domain: developer-tools, backend
- platform: go, cross-platform
- tags: xml-config, async-logging, log-rotation, log-filtering
