Hi,
I've created basic cms/ecommerce application. I've got a couple of clients that are going to use it. I'd like to find a way to maintain the same code base in the back end, but customize the front.
There are a couple different schemes I've thought of that could solve the problem.
rails engines with svn externals my own plugin scheme that kind of does what engines does, but more simple. uses svn external subversion branches? KISS - keep all of it separate - manually keep track of bug fixes, updates etc.. maybe use svn diff?
Surely a lot of you have created apps like this, where you want to have different instantiations, be able to customize, but have the ability to maintain easily?
I'm all ears
