 Methods
 -------
+Note: the following explanations are describing the usage of this extension in the OOP style, which is only
+available in PHP 5
+To use this extension in a procedural style, simply call "gnupg_init", which returns a resource.
+Pass this resource as the first parameter to each function.
+In procedural style, all methods gets "gnupg_" prefixed. (setarmor becomes gnupg_setarmor)
+Example:
+
+$res = gnupg_init();
+gnupg_setarmor($res,1);
+
+
 
 -		__construct()
 		sets up a new gnupg object
 		( new gnupg() )
 
+-		resource gnupg_init()
+		sets up a new gnupg object for procedural use and returns a resource identifier
+
 -		bool setarmor(int armor)
 		turn on/off armor mode
 		0 = off
