I have a project with many plugins and for now I keep them all in one git repository, because they consist of one file each:
plugins
+-- A
+-- B
+-- C
+-- D
+-- E
I want to deploy this software to different production systems and all of them should get different combinations of plugins. Let's say, A, B, D, C, E and B, C, D. If I change a plugin upstream, I want to update it as easy as possible on all production systems. Is there something like a .gitignore file for "do not check this files out!"? Or how can I do it without creating an own git repository for each file?
