Is there any document, article, draft sample, etc. on how to create my Base SF classes with my custom changes that can be use in all my SF applications?

I am feeling pretty confident with my SF learning and I am ready to start working on a 2nd SF project, but now I figured out that all the code I am using in my first project can not simply be copied over to the new project and I hate to keep repeating code and process when there should be a much better an efficient way to do this.

I would really appreciate if anybody can take some time to describe this subclass process in order to crate a Base set of SF classes.

hmmm, may be that could be an Enhancement Request   Sorry Trent

P.S.

I know this will be part of the upcoming SF trainning class, but I can really wait, I need to start working on the 2nd SF project ASAP.
