Generate website status report

Hi
I have been developing with codeigniter for almost two months and have been building a new CMS in order to learn the benefits and limits of the framework.
The userguide has been very helpful in getting things working, but the last thing I want to do is generate a status report like the one I have in fx. Drupal.

How would I go about this in CI 2? Are there any core implementations where I can get the information needed, is there some kind of 3rd party add-on that can make this work or do I have use "normal" PHP to get this information?

I've heard of Drupal but I don't know what the feature you're talking about it. Can you describe what the status report would look like, what information would it contain?

Hey, don't work without a PHP debugger. Several free IDEs have this features built in. Two are NetBeans and CodeLobster. Without a debugger, it's like you're driving with a blindfold on -- you are going to crash!

The main things I want from the Drupal status report are these things:
Database server and version
PHP GD library status and version
PHP memory limit in a form where it can be compared to another numeric value
Unicode library in use

There are other things, but those I have already figured out
