Welcome to packs! packs are a simple ruby specification for an extensible packaging system to help modularize Ruby applications.
A pack (also called package) is a folder of Ruby code with a package.yml at the root that is intended to represent a well-modularized domain, and the rest of the rubyatscale ecosystem is intended to help make the boundaries between a pack and any other more clear.
Here are some example integrations with packs:

A ruby gem is the Ruby community solution for packaging and distributing Ruby code. A gem is a great place to start new projects, and a great end state for code that's been extracted from an existing codebase. packs are intended to help gradually modularize an application that has some conceptual boundaries, but is not yet ready to be factored into gems.
