Thank you all for your responses and critiques.

I see most of them focus on PDO and the handling of the config file, and also the file hierarchy. I will certainly take into consideration most of them, as we want it to be something usable before all.

The responses for most of the questions are already included in the docs, but unfortunately some are not, like the use of the cache features, they are commented in the config files though.

I have spent a lot of time, but I developed the code and wrote the docs 99% by myself, so any contribution would be highly appeciated.
