+       help
+         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.
