+librsaref.so is a demonstration dynamic engine that does RSA
+operations using the old RSAref 2.0 implementation.
+
+To make proper use of this engine, you must download RSAref 2.0
+(search the web for rsaref.tar.Z for example) and unpack it in this
+directory, so you'll end up having the subdirectories "install" and
+"source" among others.
+
+To build, do the following:
+
+ make
+
+This will list a number of available targets to choose from. Most of
+them are architecture-specific. The exception is "gnu" which is to be
+used on systems where GNU ld and gcc have been installed in such a way
+that gcc uses GNU ld to link together programs and shared libraries.
+
+The make file assumes you use gcc. To change that, just reassign CC:
+
+ make CC=cc
+
+The result is librsaref.so, which you can copy to any place you wish.
