// This commit module is meant to be used if you want to commit a
// calibration to the database. This should be THE VERY LAST MODULE
// inserted in the module pipeline. 
//
// The finish method is the only one used. The parameter element
// manager will commit from the start time of the initial run and the
// end time of the final run (they can be the same run)

// $Log: BrDbCommitModule.cxx,v $
// Revision 1.3  2001/10/08 11:29:49  cholm
// Changed to use new DB access classes
//
// Revision 1.2  2001/07/19 10:53:02  ouerdane
// Added return statement after Fatal statement in Finish method
//
// Revision 1.1  2001/07/18 16:19:30  ouerdane
// Added 2 classes in this directory (modules/util)
//  BrDbUpdateModule
//  BrDbCommitModule
//
// The 1st one updates the calibration parameter manager and the run info manager
// The 2nd commit new calibration to the database, given a start run and an end
// run (they can be the same).
//
// See email on the brahms-soft/dev-list for more details on how to use them.
//
// Updated Makefile.am, LinkDef.h, Include.h for the classes to compile
//
