 * Description: sample top-level code sould be used as a tutorial
 *              for any application using the StDaqLib class library
 *      
 *
 *   change log
 *  02-Jul-99 MJL remove #include "StDaqLib/TPC/MemMan.hh"
 *  09-Jul-99 MJL add calls to various non_TPC detector readers
 *  12-Jul-99 MJL add calls to getSpacePts()
 *  20-Jul-99 MJL use new EventReader constructor with log file name
 *
 ***************************************************************************
 * $Log: client.cxx,v $
 * Revision 1.13  2003/09/02 17:55:34  perev
 * gcc 3.2 updates + WarnOff
 *
 * Revision 1.12  2003/01/29 20:08:09  geurts
 * disabled usage of TRG_Reader::PrintAllTheData() and ::PrintDataCompact().
 * Both methods are unavailabe in TRG_Reader.
 *
 * Revision 1.11  2003/01/29 13:55:18  ward
 * Turn off memory mapped operation in the examples, which appears to fail for 2003 daq files.
 *
 * Revision 1.10  2000/07/03 16:03:17  ward
 * Minor improvements to client.cxx, eg a usage message.
 *
 * Revision 1.9  2000/06/08 12:45:10  jml
 * Added <assert.h> to fix compile error in offline
 *
 * Revision 1.8  2000/06/07 15:06:26  jml
 * Changed exit() calls to assert(0) to aid in debugging
 *
 * Revision 1.7  2000/01/14 17:54:26  levine
 * example use of TRG_Reader
 *
 * Revision 1.6  2000/01/04 20:55:05  levine
 * Implemented memory-mapped file access in EventReader.cxx. Old method
 * (via seeks) is still possible by setting mmapp=0 in
 *
 *      getEventReader(fd,offset,(const char *)logfile,mmapp);
 *
 *
 * but memory-mapped access is much more effective.
 *
 * Revision 1.4  1999/07/21 21:33:10  levine
 *
 *
 * changes to include error logging to file.
 *
 * There are now 2 constructors for EventReader:
 *
 *  EventReader();
 *  EventReader(const char *logfilename);
 *
 * Constructed with no argument, there is no error logging. Supplying a file name
 * sends all diagnostic output to the named file (N.B. opens in append mode)
 *
 * See example in client.cxx for constructing a log file name based on the
 * datafile name.
 *
 * It is strongly advised to use the log file capability. You can grep it for
 * instances of "ERROR:" to trap anything noteworthy (i.e., corrupted data files).
 *
 * Revision 1.3  1999/07/10 21:31:33  levine
 * Detectors RICH, EMC, TRG now have their own (defined by each detector) interfaces.
 * Existing user code will not have to change any calls to TPC-like detector
 * readers.
 *
 * Revision 1.2  1999/07/07 19:24:37  levine
 * Added comments on using 8-bit to 10-bit translation table by popular request
 * (well, at least one person requested this change)
 *
 * Revision 1.1  1999/07/02 20:40:57  levine
 * Moved to examples directory from top-level
 *
