In Chapter 3, Branching, Merging, and Options, we mentioned that you can set a description to your branch, and this information can be retrieved from a script using the
git config --get branch.<branchname> description command. In this example, we will take this information and use it for the commit message.

We need a clone and a branch to get started on this exercise, so we will clone
jgit again to the
$ git clone https://git.eclipse.org/r/jgit/jgit ...
