## What it is
A Go library for writing system daemons on UNIX-based operating systems. It provides goroutine-safe daemonization, pid-file management, and system signal handling by re-executing the process with a marker environment variable instead of using fork.

## Use cases
- turn a Go program into a background daemon
- manage pid files for a long-running service
- handle system signals in a daemonized Go process
- run a background worker on Linux or macOS
- control and release a daemon process safely

## When to choose
- you need to daemonize a Go application on Linux or macOS
- you want built-in pid-file handling and signal management
- you need goroutine-safe daemonization without fork

## When to avoid
- you need Windows daemon support
- you need a full service manager rather than a daemonization library
- you require guaranteed backward compatibility before a v1.0 release

## Facets
- artifact type: library
- maturity: stable
- function: developer-tools, concurrency, file-system
- domain: developer-tools, operating-systems, backend
- platform: go, cli
- tags: daemonization, pidfile, unix, system-daemon, signal-handling, linux, macos
