Build a prototype of a package management application. Eventual use cases are:

• Distributing arcanist extensions (like linters and commands).
  • Particularly, making it easy for repositories to specify extensions/dependencies and have arc automatically manage them, so you can build an in-house linter and use it in all your projects.
• Distributing third-party (or maybe unbundled first-party) Phabricator applications.

These are long-term goals, particularly application management.

This is primarily blocked by choosing a cool name.
