List of changes between v4_1 and v4_2 
 
driver
  gustep.F
    ramberg:  Make appropriate new calls to MVS gustep routine
 
driver/doc
  ckmgeant.html
    jurgen:   explain use of cvs with ssh
              update for v4_2
 
mvs
  mvs_geom.F
    ramberg:  Changed copy number for GSPOS of MVPB volume.
    ramberg:  New MVS geometry which incorporates both X or Y strips of 
              scintillatorin each of 26 layers.
  mvs_gukine.F
    ramberg:  Zero out data arrays in MVS system for each event.
  mvs_guout.F
    ramberg:  New output for MVS system includes energy in scintillator strips
  mvs_gustep.F
    ramberg:  New MVS gustep routine that adds energy into data array:
               e_mvs_strips(nlayers,nstrips), where
                  nlayers = 26  (odd layers are X view, evens are Y)
                  nstrips = 50  (4 cm wide strips making a total width
                                                of the detector to be 2 m)
  mvscom.inc
    jurgen:   Added cvs headers
    ramberg:  New include file that contains the geometry information for the 
              MVS system:  nmvs_layers  (# of layers along beam direction) and
                           nmvs_strips  (# of strips - either X or Y view)
  mvsdata.inc
    ramberg:  New data structure for MVS system includes energy in each 
                strip of scintillator.
  MVS_read.F
    ramberg:  New MVS read routine to go with new MVS package
 
read
  VVS_read.F
    ramberg:  Add reading in of new vvhit_time information associated with 
                hit phototubes.
  richana.inc
    jurgen:   recalibrate for no mirror hole
 
rich
  prch_geom.kumac
    jurgen:   remove mirror hole
 
vvs
  vvs_gukine.F
    ramberg:  Change zeroing of vvs_pmt array to account for larger array 
                bounds associated with time entry.
  vvs_guout.F
    ramberg:  Add one extra output per line of hit phototubes, indicating 
                time of energy deposit.
  vvs_gustep.F
    ramberg:  This version has 2 significant changes:
              1) Fix problem with check on entrance of tracks into VVS detector
                 (hardwiriing of names(7) --> names(nlevel) )
              2) Add an extra element associated with the phi segment 
                 phototubes that contains the time of first energy 
                 deposition (i.e. the array vvs_pmt(4,...) goes to 
                 vvs_pmt(5,...) ).  The caveat is that 'first' in this case 
                 means the first time GEANT deposits energy there, not
                 necessarily the earliest time.
  vvscom.inc
    ramberg:  Two changes:
              1)  Add extra row to vvs_pmt for time variable associated with
                  energy deposit
              2)  Create new array vvhit_time that contains copy of this time
                  variable for output purposes.
