+# Quick instruction:
+# To build against an OpenSSL built in the source tree, do this:
+#
+#    make OPENSSL_INCS_LOCATION=-I../../include OPENSSL_LIBS_LOCATION=-L../..
+#
+# To run the demos when linked with a shared library (default):
+#
+#    LD_LIBRARY_PATH=../.. ./server-arg
+#    LD_LIBRARY_PATH=../.. ./server-cmod
+#    LD_LIBRARY_PATH=../.. ./server-conf
+#    LD_LIBRARY_PATH=../.. ./client-arg
