 *$Log: not supported by cvs2svn $
 *Revision 1.5  2000/05/11 13:58:42  blanch
 *This version of camera.h owns to the version 1.8 of camera.cxx.
 *
 *Revision 1.4  2000/02/18 17:42:39  petry
 *This version includes drastic changes and belongs to camera.cxx 1.5.
 *It is not yet finished and not immediately useful because the
 *trigger simulation is not yet re-implemented. I had to take it
 *out together with some other stuff in order to tidy the whole
 *program up. This is not meant as an insult to anyone. I needed
 *to do this in order to be able to work on it.
 *
 *This version has been put in the repository in order to be
 *able to share the further development with others.
 *
 *If you need something working, wait or take an earlier one.
 *See file README.
 *
 *Revision 1.3  1999/11/11 20:29:29  harald
 *Small changes to run the new version on a linux machine.
 *
 *Revision 1.2  1999/11/10 07:42:41  harald
 *Small change to read the right data files in.
 *
 *Revision 1.1.1.1  1999/11/05 11:59:31  harald
 *This the starting point for CVS controlled further developments of the
 *camera program. The program was originally written by Jose Carlos. 
 *But here you can find a "rootified" version to the program. This means 
 *that there is no hbook stuff in it now. Also the output of the
 *program changed to the MagicRawDataFormat. 
 *
 *The "rootification" was done by Dirk Petry and Harald Kornmayer. 
 *
 *Revision 1.3  1999/10/22 15:32:56  petry
 *tidied-up version, really sent to H.K. and N.M., 22-10-99
 *
 *Revision 1.2  1999/10/22 15:01:28  petry
 *version sent to H.K. and N.M. on Fri Oct 22 1999
 *
 *Revision 1.1.1.1  1999/10/21 16:35:10  petry
 *first synthesised version
 *
 * Revision 1.8  1999/03/15  14:59:06  gonzalez
 * camera-1_1
 *
 * Revision 1.7  1999/03/02  09:56:11  gonzalez
 * *** empty log message ***
 *
 * Revision 1.6  1999/01/14  17:32:40  gonzalez
 * Added to camera the STDIN input option (data_from_input)
 *
