//  $Log: BrDetectorParamsBase.cxx,v $
//  Revision 1.2  2001/09/23 01:46:52  videbaek
//  Mainly cosmetic changes, in regard to log information and
//  some in regard toi override in derived classes
//
//  Revision 1.1.1.1  2001/06/21 14:55:17  hagel
//  Initial revision of brat2
//
//  Revision 1.8  2001/06/04 13:36:06  cholm
//  Changes to use BrPathManager, BrVersion, and perpare to use BrFileTag.
//
//  Revision 1.7  2000/12/27 21:34:48  videbaek
//  Moved cvs log
//
//  Revision 1.6  2000/04/06 20:17:47  cholm
//  Added the classes BrAppOption, BrAppOptionManager, and
//  BrDetectorList. The first two are for command line processing,
//  the third for easy detector list, can be used for many purposes.
//
//  Revision 1.5  2000/03/21 21:21:41  cholm
//  Several changes: A few hacks where needed to compile on Digital Unix, noticably in my - Christian Holm - classes for the DB and Exceptions. Proberly still need to do something to some of Konstantins stuff. Also, I removed a lot of warnings fromt the compiler, by teddying up the code. Several places, old C-style indecies in for loops were assumed. Corrected. Unused variables have been commented out.
