+	  When using flat shared libraries, every library has a unique
+	  system-wide identifier.  Identifier 0 is reserved for
+	  executables and true shared libraries have identifiers
+	  starting at 1.  The maximum shared library identifier is
+	  determined by the kernel and is usually 3.  Shared library
+	  N must be available on the target system as "/lib/libN.so".
+
+	  When a shared C library is used, it usually has identifier 1,
+	  but you can use this option to select a different identifier
+	  if you need to.
