## What it is
g is a command-line tool for managing and switching between multiple versions of the Go programming language environment on Linux, macOS, and Windows. It supports listing, installing, uninstalling, and switching Go versions, plus cache clearing and self-updating.

## Use cases
- install multiple versions of go
- switch go version on the command line
- manage golang toolchain versions
- uninstall old go releases
- list available go versions for installation
- set up go version manager on windows
- mirror go downloads behind a proxy

## When to choose
- you need to work across projects requiring different Go versions
- you want a lightweight, single-binary version manager for Go on Linux, macOS, or Windows
- you need to download Go releases from a mirror such as golang.google.cn
- you want simple shell-based switching without extra runtime dependencies

## When to avoid
- you only ever use one Go version and are happy with the official installer
- you need a polyglot version manager covering many languages (use asdf or mise instead)
- you rely on Go's built-in toolchain directive in go.mod for automatic version selection
