## What it is
Bundler is the standard dependency manager for Ruby applications, tracking and installing the exact gems and versions a project needs via a Gemfile and Gemfile.lock. This repository is the historical home of Bundler, which has since been merged into and maintained within the rubygems/rubygems repository.

## Use cases
- manage gem dependencies for a ruby application
- lock exact gem versions so every machine runs the same code
- install gems listed in a Gemfile with bundle install
- update project gems to newer compatible versions
- run executables in the context of the bundle with bundle exec

## When to choose
- you are building or maintaining a Ruby application with external gem dependencies
- you need reproducible gem installs across development, staging, and production
- you want automatic dependency resolution and version compatibility checks for gems

## When to avoid
- you are not working in the Ruby ecosystem
- you need to contribute to Bundler development - the project now lives in rubygems/rubygems
- you need a general-purpose package manager for non-gem artifacts

## Facets
- artifact type: library
- maturity: maintenance
- function: package-manager, dependency-audit, cli, developer-tools
- domain: developer-tools, version-control, programming-languages
- platform: ruby, cross-platform, cli
- tags: rubygems, gem-dependencies, gemfile, dependency-management, ruby-ecosystem, command-line
