+						 cannot be redefined by another shared library or executable. This mode is

+					-> Hidden:
+						- Hidden symbols are not exported from shared libraries and cannot be 
+						 redefined by a different shared library or executable loaded in a process.
+						 In this mode, public symbols have to be explicitly marked in the source code
+						 to be exported from shared libraries. This is the recommended mode.
