+3.12 SILC Version Detection
+
+The version detection of both client and server is performed at the
+connection phase while executing the SILC Key Exchange protocol.  The
+version identifier is exchanged between intiator and responder.  The
+version identifier is of following format:
+
+.in 6
+SILC-<protocol version>-<software version>
+.in 3
+
+The version strings are of following format:
+
+.in 6
+protocol version = <major>.<minor>
+software version = <major>[.<minor>[.<build>]]
+.in 3
+
+Protocol version may provide both major and minor version.  Currently
+implementations must set the protocol version and accept the protocol
+version as SILC-1.0-<sotware version>. 
+
+Software version may provide major, minor and build version.  The
+software version may be freely set and accepted.
+
+Thus, the version string could be, for example:
+
+.in 6
+SILC-1.0-1.2
+.in 3
