      PROGRAM BLOTII
C=======================================================================

C                         *** BLOT ***

C   --*** BLOT *** (BLOT) Post-processing plot program
C   --
C   --BLOT is a graphics program for post-processing of finite element
C   --analyses output in the EXODUS II database format.  BLOT combines the
C   --plotting capabilities of DETOUR, TPLOT, and SPLOT.  It is command
C   --driven with free-format input.  BLOT can drive any graphics device
C   --supported by the Sandia Virtual Device Interface.
C   --
C   --DETOUR produces mesh plots with various representations of the
C   --analysis output variables. The major capabilities of DETOUR are
C   --deformed mesh plots, line contours, filled (painted) contours,
C   --vector plots of two variables (e.g., velocity vectors), and symbol
C   --plots of scalar variables (e.g., discrete cracks). DETOURs features
C   --include element selection by element block, element birth and death,
C   --multiple views for combining several displays on each plot, and
C   --symmetry mirroring.
C   --
C   --TPLOT generates time-versus-variable plots or variable-versus-variable
C   --plots where the variables are user-selected global, nodal or element
C   --EXODUS database variables.  TPLOTs features include multiple curve
C   --plots and neutral file output.
C   --
C   --SPLOT generates distance-versus-variable plots at selected time steps
C   --where the distance is the accumulated distance between pairs of nodes
C   --or element centers and the variable is a nodal or element EXODUS
C   --database variable.  SPLOTs features include multiple curve plots
C   --and neutral file output.
C   --
C   --Plot times from the database are processed in one of the following modes:
C   --   Uniform time interval - plot at every DELT time interval from
C   --      TMIN to TMAX.
C   --   All available times - plot at all available times from TMIN
C   --      to TMAX.
C   --   User selected times - plot at user selected times.
C   --The closest available time step is chosen.
C   --
C   --Expected input:
C   --   o The commands on the standard input device.
C   --   o The input EXODUS database on unit 11.
C   --
C   --Output:
C   --   o A listing of the input database information and any errors
C   --     found on the standard output device.
C   --   o The plots on the specified graphics device.
C   --   o A GRAFAID neutral file on unit 20.
C   --   o A EXPLORE listing file on unit 21.
