  * CI_BASE - For PHP 4

- * This file is used only when Code Igniter is being run under PHP 4.

+ * This file is used only when Code Igniter is being run under PHP 4.
+ * 
+ * In order to allow CI to work under PHP 4 we had to make the Loader class 
+ * the parent class of the Controller Base class.  It's the only way we 
+ * could enable functions like $this->load->library('email') to instantiate 
+ * classes that can then be used within controllers as $this->email->send()
+ *
+ * PHP 4 also has trouble referencing the CI super object within application 
+ * constructors since objects do not exist until the class is fully
+ * instantiated.  Basically PHP 4 sucks...
+ *
+ * Since PHP 5 doesn't suffer from this problem so we load one of 
  * two files based on the version of PHP being run.
