// Revision 1.1.1.1  2001/06/21 14:55:10  hagel
// Initial revision of brat2
//
// Revision 1.4  2000/02/11 00:14:05  hagel
// 1. Updated to the latest version of all of Konstantin's online routines
// 2. Changed ZDC to use updated recordId's which return 8 adc values in
//    one recordId.
// 3. Added an alpha-alpha version of unpacking for RICH.  It is mostly
//    placeholder, but will serve as ground work to quickly get unpacking
//    once I understand what needs to be unpacked and what the raw structure is
//
// Revision 1.4  1999/05/30 01:58:53  olchansk
// Added code for handling Filemark-vs-EOD errors
//
// Revision 1.3  1999/05/27 16:22:22  olchansk
// Removed all use of std::string from BrRawIO.
// Corrected the affected example programs.
//
// Revision 1.2  1999/05/21 20:00:55  olchansk
// Intergrate BrRawEvent into the event builder.
//
// Revision 1.1  1999/05/14 23:31:51  olchansk
// New versions for data IO and record access libraries.
// This is new, untested code.
