25
 * This version of the NINDY interface routines supports NINDY versions
26
 * 2.13 and older.  The older versions used a hex communication protocol,
27
 * instead of the (faster) current binary protocol.   These routines have
28
 * been renamed by prepending the letter 'O' to their names, to avoid
29
 * conflict with the current version.  The old versions are kept only for
30
 * backward compatibility, and well disappear in a future release.
