Though missing a bit of explanation: @stillyslalom is correct when stating that Julia [packages] are typically just a single “module” (even if it might apply to “projects” that are not simultaneously “packages”). I say this because the terms you are used to might not have the same meaning in Julia.

The main reason why this is a correct statement is that a Julia “module” is actually what you would call a “namespace”. It does not represent a “software module”.

I have made a few additional posts that might help you:

(Though you might not want to read about “Multi-package repositories” at this time)
