I noticed a few comments to the effect that Zend.php makes a good
entry point into the framework. I really don't see how this is the
case. The entry point for anyone wanting to get a grasp on the
framework is the bootstrap file not Zend.php.
If anything Zend.php is a confusing class that immediately presents
beginners with exceptions to the general framework setup. I think
Ralf Eggert has nailed it in his component breakdown and in
comparison to "Zend" would be easier to understand since...
Zend_Registry
Zend_Loader
Zend_Debug
...are relatively self explanatory. They are also the kind of classes
that many of us probably already have in previous frameworks to one
degree or another.
