Barrel is a simple cms. It's design is inspired by drupal. Writing barrel module is as simple as writing drupal modules.
You can just download this project and put into your public web directory. You may want to create an admin using using the Makefile in scripts directory.
make user_create
You have a builtin filedatabase. And a playtool script to do things in shell.
You may play with the modules and let me know what you think.
