 * $Log: client_svt.cxx,v $
 * Revision 1.1  2007/01/04 21:27:52  jml
 * zero suppressed reader no longer uses adcx, only seqd.  Fixes bug from early 2005
 *
 * Revision 1.3  2003/09/02 17:55:34  perev
 * gcc 3.2 updates + WarnOff
 *
 * Revision 1.2  2003/01/29 13:55:18  ward
 * Turn off memory mapped operation in the examples, which appears to fail for 2003 daq files.
 *
 * Revision 1.1  2001/04/18 19:49:32  ward
 * Added SVT example program client_zs.cxx from J. Schambach.
