/**
 * This defines the overall protocol version that this build of libguac
 * supports.  The protocol version is used to provide compatibility between
 * potentially different versions of Guacamole server and clients.  The
 * version number is a MAJOR_MINOR_PATCH version that matches the versioning
 * used throughout the components of the Guacamole project.  This version
 * will not necessarily increment with the other components, unless additional
 * functionality is introduced that affects compatibility.
 * 
 * This version is passed by the __guac_protocol_send_args() function from the
 * server to the client during the client/server handshake.
