## What it is
A Go library providing zero-downtime restarts for HTTP and HTTPS servers. It acts as a drop-in replacement for http.ListenAndServe, handling graceful restarts via signals like SIGHUP.

## Use cases
- deploy new Go server binaries without dropping connections
- gracefully restart an HTTP server on SIGHUP
- run multiple servers from one binary with socket handoff on restart
- terminate hanging requests after a grace period during shutdown
- hook custom code before or after restart signals

## When to choose
- you run a Go HTTP/HTTPS server directly (no reverse proxy) and want zero-downtime restarts
- you want a minimal code change replacing http.ListenAndServe
- you need signal hooks and configurable shutdown/hammer behavior

## When to avoid
- your server sits behind a load balancer or reverse proxy that already handles rolling restarts
- you need actively maintained alternatives with broader features (e.g. oklog/run or built-in graceful shutdown in modern frameworks)
- you are not serving HTTP/HTTPS from Go
