+ * DESCRIPTION
+ *
+ *    This utility function can be used to parse the remote host's version
+ *    string.  This returns the protocol version, and software version into
+ *    the `protocol_version', `software_version' and `vendor_version' pointers
+ *    if they are provided.  The string versions of the versions are saved
+ *    in *_string pointers if they are provided.  Returns TRUE if the version
+ *    string was successfully parsed.
