What is a full name of the rbs?

Is the rbs an abbreviation of something right? What is the full name of the rbs?
Is the full name "RuBy Structure" (the README.md says "RBS is a language to describe the structure of Ruby programs") or "RuBy type Signature" (the rbs.gemspec summary says "Type signature for Ruby.") ?

For example I assume a full name of the irb is "Interactive RuBy".

When I wanted to create a document to explain the rbs, I had the question.

I don't think RBS is an acronym of a full name. It implies a combination of RuBy and Signature, but it's not the full name.

I guess it's similar to RPM (is not Redhat Package Manager), PHP (is not Personal Homepage Page tools), or OCaml (is not Objective Caml).

All right. Thanks for the answer. I would close this ticket.

As a reference, in case of RPM, I think it was an acronym of "Red hat Package Manager", now it is an acronym of "RPM Package Manager".
