How to add your libraries to Composer for use in different projects?

Question

PHP

There is a set of own libraries which I use in different projects. Now I'm trying to figure it out with Composer, I'm interested in the possibility of loading my libraries from private repositories.
1. Is this possible?
2. How to format the json file for this?
3. How to format your libraries so that they can be easily used in Composer?

Well, in general, it's easier to specify the git repository directly:

"repositories": [
    {
      "type": "git",
      "url": "....git"
    }
]
