How to facilitate the process of creating versions of modules?

Question

CMS

Good afternoon!
For a long time I have been writing modules for CMS as a hobby, and a little money is dripping. All this of course under Windows.
I have never been interested and now I want to ask experts what can help in facilitating the process of creating new versions of modules?
We have a module of 10 files for different versions of one CMS. Having implemented everything for the latter, the work for the rest follows (actually copying).
It takes a lot of time to constantly copy and paste the same element for each version of the CMS.
I don't know which way to dig and what can help facilitate the process :) Can you tell me?

Answer 1

So copy. It is unlikely that it will be possible to single out some kind of module core in order to please everyone.

Answer 2

composer
