Plugin or just a zip file

Hi ,

I am thinking of having a plugin to provide the updates to a set of
around 20 ruby file I ship with my rails application. I plan to place
the files in vendor/plugins/test folder…

Should I make test as a plugin or just provide updates in a zip file?

What is the rails suggested way. These files are only used as include
files for a few operations, they in no way are required to alter
Model/View or Controller.

Thanks,
Sudhindra
