-   Code developed by S. C. Phatak, Institute of Physics, 
-   Bhubaneswar 751 005 ( phatak@iopb.res.in ) Given the energy deposited
-   ( or ADC value ) in each cell of supermodule ( pmd or cpv ), the code
-   builds up superclusters and breaks them into clusters. The input is 
-   in array d[ndimx][ndimy] and cluster information is in array
-   clusters[5][5000]. integer clno gives total number of clusters in the 
-   supermodule.
-
-   d, clno  and clusters are the only global ( public ) variables. Others 
-   are local ( private ) to the code. 
-
-   At the moment, the data is read for whole detector ( all supermodules
-   and pmd as well as cpv. This will have to be modify later )
-
-   LAST UPDATE  :  October 23, 2002
