Git tagging cookbook

Let's suppose that we want to keep two different tag versioning on the same repo:

• v[0-9]* for master branch versions
• d[0-9]* for development branch versions

Basic commands: https://git-scm.com/book/en/v2/Git-Basics-Tagging

Multiple gem versions

While developing a serialization gem I needed to compare my current code with previous gem versions.

(Un)fortunately bundler does not allow to install several versions of the same gem to prevent conflicts on class names. The purpose of this script is to wrap a gem into a namespace/module named.

You should set in the main script:

• L7 TARGET_DIR: the dir where the gems will be extracted
• L8 PKG_DIR : the dir where the .gem files will be downloaded
