## What it is
A standalone prototype of a version-aware `go` command that brought Go 1.11 module support to users on Go 1.10 toolchains. It is now obsolete, as all of its features were incorporated into the main Go toolchain.

## Use cases
- manage Go project dependencies with semantic versioning on Go 1.10
- try out Go modules before upgrading to Go 1.11
- experiment with versioned Go workflows
- resolve and download specific versions of Go packages

## When to choose
- you are stuck on a Go 1.10 toolchain and need module support (historical scenario only)
- you are studying the history of Go's module system design

## When to avoid
- you use Go 1.11 or later - modules are built into the standard `go` command
- you are starting a new project
- you need maintained tooling

## Facets
- artifact type: cli-tool
- maturity: abandoned
- function: package-manager, build-tool, cli, developer-tools
- domain: developer-tools, version-control, programming-languages
- platform: go, cross-platform, cli
- tags: go-modules, dependency-management, versioned-go, obsolete, historical, command-line
