+/**
+ * CI_BASE - For PHP 4
+ *
+ * This file is used only when CodeIgniter 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 of the Controller Base class.  It's the only way we can
+ * 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.
