+ * Returns the current URL path of the page being viewed.

+ * Example #1: On viewing http://example.com/node/306 this function
+ * returns "node/306".

+ * Example #2: On viewing http://example.com/drupalfolder/node/306 this

+ * Example #3: On viewing "http://example.com/path/alias" which is a path
+ * alias for "http://example.com/node/306", this function returns "node/306" 
+ * as opposed to the path alias.
+ *
+ * NOTE: This function is not available in hook_boot and you should use
+ * $_GET['q'] instead. Also, be careful in the case of Example #3 if you
+ * use it in hook_boot as it will contain "path/alias". Calling
+ * drupal_bootstrap(DRUPAL_BOOTSTRAP_PATH) makes this
+ * function available with a return value of "node/306".
+ *
+ * @return
