How I can register subdirectory of my vcs root as a bower module?

Question

I have this project structure:

- .git
- test
--- unit
--- e2e
- sources
--- lib
--- js

I have this project structure. This is some library, that I want to share with other peoples. I want to register my code as bower module, so people can easy use my library.

Actually, bower module is only /sources/* contents. I don't want test directory to be published in bower module contents. I want only /sources/* contents to be published.

Note, I know that I can ignore some directories like test/ directory. After this when I do bower install moduleName I will got this structure:

- sources
--- lib
--- js

This is not what I want. I want to get sources contents.

Also, I tried to put bower.json into sources directory. After that:

• I have problems with bower version <ver> (no tags are created)
• I resolve full project structure, but only only contents of the dir with bower.json file

How to register bower module, so only contents of some subdirectory will be published?
