Specs for repository/software function

Question

Specs for repository/software.

I saw many repository on Github or other place the repository have a Specs incidental project for it.

A few examples:

1. nova-specs for nova
2. neutron-specs for neutron
3. Specs for CococaPods

Before ask this question, I have queried many data on internet.

Wikipedia give a very brief introduction, not can explain the Specs for a repository.

in the internet there is no explain the Specs for a repo's detail explanation.

I also tried to understand the specs, only get the specifications word for it, does it just write for user to understand the repo? just like a instruction book?

If the function is only the upper, how about the Specs's specifications, is it self-defined? I saw the Specs there are three level 1,2,3,4,5,....d,e,f 16 directories in the directory framework. and the CocoaPods-Specs also have other functions, such as install configuration.

EDIT

My question is simple:

1. Whats the Specs project for a repo in Github functions?
2. Is the Specs project have specified role ? How to understand the Specs's directories about the 0, 1, 2, 3, ...d, e, f directories in it?

Answer 1

For CocoaPods, the Specs directory is the shared location for all publicly shared podspec files. More details here.

The subdirectories are used to manage the number of files in the repo so that there wouldn't be a huge number of files in one directory. The b/0/7 is generated from a hashing scheme of the podspec name.
