## What it is
UPM is a universal package manager written in Go that provides a single consistent interface for managing packages across many programming languages by wrapping their native package managers. It supports Python, Node.js, Ruby, Rust, Java, PHP, Dart, R, .NET, and Emacs Lisp, with features like dependency guessing and machine-parseable specfile/lockfile listing.

## Use cases
- add and remove packages across languages with one command
- avoid remembering pip vs poetry vs pipenv quirks
- search package indexes from the command line
- guess dependencies from project source files
- generate lockfiles uniformly across languages
- list installed packages in a machine-parseable format

## When to choose
- you work across multiple languages and want one package management interface
- you build tooling or IDEs that need programmatic package manager integration
- you want dependency guessing and parseable lockfile output

## When to avoid
- you only use one language and are happy with its native package manager
- you need advanced features specific to a single package manager
- your language or package manager is not in the supported list
