+ Note on shared libraries
+ ------------------------
+
+ For some systems, the OpenSSL Configure script knows what is needed to
+ build shared libraries for libcrypto and libssl.  On these systems,
+ the shared libraries are currently not created by default, but giving
+ the option "shared" will get them created.  This method supports Makefile
+ targets for shared library creation, like linux-shared.  Those targets
+ can currently be used on their own just as well, but this is expected
+ to change in future versions of OpenSSL.
